With the addition of Paul's new fastback, PDR has to get a move on our 66 coupe project "boxcar willie"...And in the quest for knowledge and myth busting debunking we decided to take on stripping it today using the oven cleaner method. ::

Forget the cheap stuff, this is what you need

After a good coat, and 20+ minutes, one swipe with a razor yielded this:

Yes, that's bare metal

See how some areas of paint will literally drip off?

It wasn't all easy, though. You've still got to do some scraping! Here Randy poses in front of a clean panel thinking "I'd rather be wetsanding!" ::

Heeeere's Willie. Next weekend he'll get another EZ OFF treatment and some sanding to remove the last of the tough stuff.

Just make sure you clean off ALL of the easy-off residue with a very thorough washing before trying to spray the primer and paint. BTW - how did you get rid of all the nasty goo after you scraped it off the car?

We scraped off the paint and goo, and eventually washed the whole thing down with a hose. Followed that with a spraying of Ospho (an acid wash) which would effectively neutralize the base oven cleaner and keep the exposed sheetmetal from flash rusting.

After rolling the car back into the Mardi G'rage, most of the paint/goo swept up, and then we hosed down the area to get to any stuck places.

BTW, my 8 yr old son was just looking over my shoulder, and saw the last pic of the car and it's mottled appearance. He said "Cool, an Army mustang!" Guess he thought it looked kinda camouflage! ::

So far, we've gone through about 9 cans (about $30 from Wally World). I must admit I had higher expectations from it, but It worked at least as well as Aircraft Stripper, and was much cheaper. We had up to 6 coats of paint in some places on this car.

Pros:
  • Stays wet longer than Stripper (lower VOC's, I guess)
  • Clings well to vertical surfaces
  • Less expensive than aircraft strippers
  • Cuts Through multiple layers
  • The reaction of the Lye (Sodium Hydroxide) and the weak Phosphoric Acid produces a salt and water during neutralization
Cons
  • Strong Base hard on the skin, requires protection, as does Aircraft Stripper
  • Messy, as is aircraft stripper
  • Multiple coats needed to remove heavy paint and bondo, as does aircraft stripper
  • paint/stripper mixture stays tacky for a long time

No Mark. We swept up and deposited in the trashcan the great majority of the paint and goo. We then neutralized anything else with water (see Paulwall's post). Any small residue stuck to the slab was hosed off into a large area of private property grass. Take a look at the last pic of Willie and you'll see there's not much left to hose off the slab.

Irresponsible? One could argue that simply driving and maintaining a vintage car is environmentally irresponsible (in light of the efficient or hybrid cars now available), but I'm not losing sleep over it yet. ;)
