BUICK 1964 Skylark Coupe Project

Managed to try out my new-to-me sandblaster today. Took a bit to get it tuned just right, but it works awesome. Really fast removal of paint and rust. My compressor struggles to keep up with it, which I expected, but it still ran it. It did force me to stop after a bit because the air was getting moisture in it and the blaster doesn't feed well with any moisture in it.

Did manage to find some more pinholes in the inner arch. The last few inches of the rear I'll cut out and replace, but the other ones are small and few enough that I can't see justifying cutting them out. POR-15 makes a product called POR Patch that would be ideal. Or even just seam sealer or some panel bonding adhesive. It isn't structural or visible and the metal is clean on both sides, so it just needs to be sealed.

I will tomorrow. It's a dead man switch. I don't totally love it.

POR Patch is awesome for small spot repair. They should still have the two part POR Putty that'll need some filing or light grinding to shape. I used both when I had my '72 & needed to fix the rear window area after removing what was left of the vinyl roof.

I'm a lot closer to Vice Grip Garage than West Coast Customs so for inner wheel arch pinholes, it oughta work. In regards to the Putty, there's a similar product called Belzona which is used for similar metal loss situations in much higher demand applications.

Worked on patching the outer wheelhouse today in preparation for welding the arch on. Ended up doing it in two pieces after having a ton of blow through while welding the first piece in.


Also I was able to order POR-15 Patch from my local body supply shop, it came in today. I'm planning on filling in the pinholes and seam sealing around the patch panel with it.

Sorry for taking so long with this. Here's a shot of it for you.

I added another disposable inline water filter to it as well. Blaster works really well and my compressor seems to keep up for small areas like this. I do think it could be adjusted so it doesn't go through the sand so fast, but I can't complain about the results.

Decided to give the POR Patch a shot after dinner. It really is just a very thick POR-15. For the most part, it self-levels. I kinda fugged up because I should've put a piece of duct tape behind to back it first, so I had to stop halfway through and do that. But so far, so good. I just squeezed it out on my finger with gloves and applied it with my finger. It seemed to be the least messy route. Probably will need a second coat on some spots.

I wonder if that's an add on or a change they made since I got mine?

If it was a later change, it was a downgrade. I was fighting with all day. Its very prone to leaking. A 1/4 turn shutoff would be a lot better.

Put on a second coat of the POR patch today and I'm not sure what the issue is but it is bubbling like crazy. I went straight from blasting to applying it so that the surface would be clean. Unless some contaminant came from my gloves, which were brand new out of the box, I don't know where it could've come from. Nothing I can do now but let it cure and remove it. I hate this kinda chit.
