Anyone ever use "great stuff" foam?

[joesregalproject]

Then you know it should be called "dumb sh*t". I bought a can of the waterproof kind today to fill a gap in between my original floorpan and my floorpan patch. When I got home, the first thing to go wrong was that the straw broke. I went ahead anyway (big mistake). There is no control over the product when it's coming out of the can, it flies everywhere, all over me, all over my frame & catylitic converter. So I did fill what I wanted to fill, I'll have to sand the excess off later, and scrape the over spray off of the frame & cat. As for getting it off of myself, that sh*t won't come off with gasoline and a SOS pad. So I waited for it to cure and I gotta peel it off of my skin (ouch). I got it in my hair, so guess who's gettin a buzz cut? I'm never buyin Dumb sh*t again. Anyone have a similar experience?

Why would you want to use foam on your car anyway? Fiberglass would have been a better pick for trying to fill a hole.

Squirrels got into my soffets. I filled the holes with chicken wire and Great Stuff. No more squirrels. I also used it to foam in the insides of bench seats on a skiff for flotation. I just cut the excess off with a knife. I wore latex gloves, so no problems.

I've actually used it on a winter beater years ago and it did a great job of bonding the panels together and filling the void but I was also wearing latex gloves and made sure the straw stayed on and it is best to stick with the minimun expansion stuff to avoid an even bigger mess.
It really does have many uses but I have found the cans themselves are typically a one time use can so plan accordingly.

One time I used it, the straw was clogged from a prior use, and when I tried to spray, the straw shot off and foam went everywhere. I caught hell trying to get it off my clothes, hair and hands. Matter fact, I still have the shirt, with the foam still on it, from 2 1/2 years ago.

I also found a way to reuse the can after usage. After spraying, pull the straw from the part that connects to the can and unscrew the part that connects to the can. Let the foam set up in both parts, then use a long, skinny wood screw and screw down into the straw, and the part that screws onto the can, and just pull out the hardened foam. Then you can usually just hand twist off and pull up on the small amount of foam coming out of the top of the can. 😀 I don't understand why they don't explain this in the directions. I guess they want you to keep buying cans.

i use it alot and its great.but you got to watch how much you use because of the expansion rate. it can expand enough on a window or door frame to push out on the frame and cause the door or window not to shut properly. i once even did redneck body work with it on a beat up work van. fiied the rocker then trimed it flush and a little black duct tape looked decent and held up until it was time to scrap a year later.

It wasn't a hole, it was a thin seam in between panels, it was under the car, so no ones gonna see it anyway, and I covered it with undercoating anyway. Sure it kinda looks like crap, but it holds up as well as anything , and it is foam, so it's easy to remove if need be.

lacquer thinner is what I used to get it off my hands. Use caution though. I use it for cleaning everything including my hands...ALOT. My skin is still there...er...kinda. :lol:

I used that stuff with decent success...
I broke the straw right away too, but just taped a straw from mcdonalds onto the end and that worked pretty slick.
I got it all over my fingers, but I it all came off with a long shower... though there was a glob on my thumbnail for over a month lol...

Should have use the correct stuff like 2K epoxy seam sealer which is water and rust proof. Though I do like using Great Stuff to make bloody guts for Halloween.
