Paint stripping/rust removal

[hig]

I bought this Camaro about a year ago for a project with my son and I'm wonding what the best way to strip it and remove the rust.

When I stripped my 72 I used those wolven stripping discs but the 72 had many coats and that worked well.

Should we carefully sandblast the car to remove the rust or should I use chemicals to remove the rust? I think I've read about Naval jelly but there might be other ways.

Thanks, Steve

hoods are cheep just replace it with a good one or what every kind you wont, lots of luck with the rest

that is just surface rust. 80 grit on a d/a will get it off, then clean with with wax and grease remover and spray with 2 coats of epoxy. then start your body work.

^^^^^^^
agreed, sand and prime.
Hoods are very large and relatively flat, whatever you use to remove the paint, make sure you are not creating any significant heat. Use low hand pressure, especially in the center.

I'll be using SPI epoxy primer on the bare metal, I've always wondered do I have to remove every speck of rust from the deeper pits, is it true that rust won't spread if there's no oxygen and the epoxy will seal the oxygen out? It just doesn't seem like 80 grit would get all of the rust from the pits and I do agree it's mostly surface rust.

I would agree but MOST of the car is like that!!

Rust in pits has to go.It'll come back eventually.You can soak rust treatment stuff in there,so you dont have to sand down that far.Boardog prolly has a good product to use for that.On my rebuild,I had subbed that part out to our own 70-SS/RS-L78.

I'm also interested in this in relation to SPI epoxy primer. I've heard good things about Ospho and have tried it myself and it does work well, but I know it's not recommended, by SPI, to use any converters under the SPI epoxy. I've tried naval jelly and it's really slow working, in my opinion. I have blasters, but I'm paranoid that I'll warp the panels.

Does SPI recommend or approve of ANY chemical /liquid rust treatment on
the metal before its EPOXY ????

on the pitted rust use navel jelly with plastic over it let it sit, then use a small wire brush and work it in, it will get all the rust out of the pitted metal.
