hey guys, i decided to give my cutlass a little cleaner look without the big chrome rotter mouldings, because i could see rust, and i knew that a little bit of the bottom lip on my pass. door was gone.

being a first timer, i am wondering what to do. my dad hasn't done body work either. the main issue is the pass door, but i think i might have to get a new door. the ony issues are rust around a few of those metal nail looking things, and a bit of rust on the bottom of the driver door, in front of the rear wheel wells, and behind the rear wheels on the lip where the bottom of the body is folded in and then down, i guess. the only place the rust is all the way through is the pass. door, everything else is surface.

i will hopefully have enough money to paint it by the end of the summer, but i will hopefully be driving it during the summer also. my uncle suggested i take all the paint off from the bottom line on the door down. how would i do that? should i use a DA sander or should i just get one of those paint remover pads and use our die grinder to get to bare metal? if i go bare metal there will i have to take the whole car down to bare metal? there is already metal exposed on the rockers, so i don't know what to do. i was thinking fix the rockers and prime them so i can drive it, at least there will be a body line from the old paint to primer :lol: we will have access to welding equipment, so we can fill the holes from the plastic clips and such.

i don't know body work at all, so tell me what you guys think. i need a game plan for this summer because without one, i will be lost and get overwhelmed because my dad hasn't been helping me much lately. any help is very much appreciated 🙂
 
I recently stripped my monte to bare metal, so the best thing to use is one of those stripper attachemts for your grinder. i used the da but it took for ever then i tried the pad for the grinder and huge difference in the amount of time to strip a panel. i would buy 4 of those pads and that would easily strip the entire car down
 
Think long and hard before stripping a whole car to bare metal. I stripped about 4 panels in my body work, and it is not fun! You have to be prepared to put them in a water proof primer right away, not the cheap lacquer primer they sell in spray cans. I have been using the spray can etching primer as my base, then sanding it with 400 or a red scotchbrite, then top coating it with urethane primer. The urethane primer surfacer I used is $95 a gallon with hardener, and must be sprayed from a gun. I use a $10 gun I got from Harbor Freight to spray it (in case it hardens in it, I don't ruin my good top coat gun), but remember to wear at least a dual cartridge respirator while spraying it! It is not good for your lungs, and don't get it on your skin! It is poisonous and can be absorbed through the skin. Wear rubber kitchen gloves at minimum while mixing, spraying, and cleaning the gun. Use the respirator at this time as well to keep from breathing it.

I would strip the panels only in the sections you need to by using a flapper disc on an angle grinder. It is gentle on metal, but rough on paint if you use it right. It also does not build heat quickly, so warpage is kept down. I use them to cut down welds slowly, and also used one to partially strip a fender with 4 paint jobs, but stopped short of bare metal. I used Aircraft Remover for that. Again, if you use it, KEEP IT OFF YOUR SKIN!!! Keep a garden hose nearby for when it does touch your skin. It will start to give you chemical burns and you will definitely feel it. Water neutralizes it, so spraying it off will minimize any damage to your skin. Again, I would not chemically strip the car as it opens up a Pandora's box of problems. I did it only to panels I had removed from the car in order to localize where the stripper went. It will damage any seals, rubber, or plastic it touches, so use with extreme caution or you could do more harm than good.

To remove the studs for the trim, try this: Clamp on them with some vise grips and twist them off by rotating them parallel to the metal. Don't buckle the metal though, or you risk more work to straighten it back out. Then, any remaining metal can be ground smooth with the flapper disc. Finish the area with a skim coat of filler, then level it using a air file with a 80 grit sheet, followed by hand sanding with 220 grit wet or dry. Then, you are ready for primer.

BTW, I am about 400 hours into my body work with another 100-200 left to go before I am ready for paint. This is with a car that is off the road. If you want to look, my Myspace has about 100 pics of the progress. I also have a build thread chronicling my progress. Links to both are in my sig.

Here's a flapper disc strip job before chem strip.

thanks for all the good info! that is very very useful!!

I dont think i'm going to strip the whole car down now. what do you think i should do then? like i said, from that bottom line down, the doors mostly, and behind the door are the only big spots for rust. a lot of the bottom edge is rusted along with where most of those studs were. do you think i should take all the paint off from that line down, if i do take all the paint off down there, how would i build it all back up? or should i use a DA sander and just sand it and build those areas back up with filler. would short strand fiberglass bondo be a good choice because i just bought a big can of it for my trunk seam. any other different methods to suggest?

sorry for all the questions, but again thanks for all the info!
 
Fiberglass filler is a very butch way to do it, and it won't last. You will want to replace the rusted metal with metal. After securely attaching it, and grinding the welds flush, then use the Fiberglass bondo to seal it against rust on the top side, and some sort of sealer on the back side to keep out moisture. After that, the sanding will help you feather in the old paint and the filler to make a smooth repair. It will take more than one application to get it right. Also, when working with anything fiberglass, wear at a minimum a dust mask. Breathing in fiberglass sanding dust can damage your lungs. I usually top coat my fiberglass filler with standard bondo as my second stage. Standard filler does not seal out moisture, but it is safer to work with. Also, if you lack welding equipment, you can make lap joints and put it all together with Panel Bond. Get yourself an Air File too. It is much more useful on a G body than a DA as it allows you to get straight body lines right. They are under $40 at Harbor Freight. Anyhow, I gotta get back outside and spray some primer!
 
the rust isn't all the way through anywhere except the pass. door.

i don't think i would be able to fix rust holes with bondo. i wouldn't be able to look at my car without feeling sorry for it.

i'll just even out the rust with regular bondo or something. i think i will get a new door, but if it is able to be fixed, a good friend of our family will probably do it, due to mine and my dad's lack of body work knowledge.

do you think i should DA the surface rusty sections, build them up with some bondo to get to them to be the same height as the paint and them have someone primer it and paint it quickly for a temporary job? as i don't have enough to do the whole car.

good luck with your primer-ing!
 
Well, you want to get rid of all the rust before putting Bondo on the pits. I use Naval Jelly, after first grinding it down with a flapper disc and a wire wheel. Sand blasting works well too. Usually, I get it to gray metal before I put filler on it. If you need to do a hole without welding, you can use JB Weld to hold the patch in place.

Oh, and I have new pics of the finished primer job in my build thread...
 
again, thanks for all the very useful info, that definitely pointed me in the right direction.

i will probably pick up some of that jelly then, clean all the surface rust and then have someone prime and top real quick after i get the surface even with bondo

the paint on the rockers will just have to last me this summer, then i will have enough time and $ to do the whole car!!

what do you guys think as far as color choices? I was thinking an off white or cream ( i saw it on another olds, it is a factory color). can i get any 1 stage pearl paint? maybe an off white pearl would be cool. keep in mind the brown vinyl and interior are staying. if i go with a color other than brown, should i leave the rally wheels brown to highlight the vinyl? let me know what you guys think, i need other viewpoints than my own. this will be a tough decision!
 
For first time paint and body work, don't expect it to come out too good. So, a single stage straight white would be my choice. No pearls, etc. That will also keep costs down, and should you decide to have a do-over, it won't hurt too bad. Also, white hides flaws better than any other "color", which is why I use it on my beaters when I want them to look OK for a long time. Dark colors are a no-no until you know how to do body work damn near perfect, since black, etc. will show every single minor imperfection.

My first experience with paint prepping was BAD. It really took me 2 or 3 times before I had a car that looked acceptable. Now, my stuff is show quality when I spend the time, but it takes A LOT of time. And Money. I should post a pic of all the different tools I have used to do this car, probably 10-15 of them in all. Many are borrowed from my neighbor that I help from time to time. I do better body work than he does, but he has more tools than me. We disagree on many things, but help each other out when needed.
