Did a frame-off nut twisting, bolt churning, restoration of my TR3A. Sawed the
body in half to get it off the frame...easy because the rockers and floors were
mostly gone anyway! Suspect am proud possessor of the PowerBlaster Award for
number one user at one point.
Used phosphoric acid in gallon jugs from, ISTR, Home Depot or Lowes. Diluted
and in spray bottles. Dave is right. Burns like crazy when it gets on your
skin, but a trick I learned was to be clumsy with POR 15 such that your hands
are coated, thus protected. That's my story and I'm sticking to it....
Directions on the jug were pretty clear. Leave the part wet with it for 10 -
15 minutes, something like that, then hose off or spray liberally with the
bottle. Let dry, then it's ready to prime and paint. I think it's been 10
years now, with daily driving when there's no snow. No issues with paint
peeling or any of that. Painted surfaces look great, but then I'm not a
concourse type so claim no true judgment here.
Worked for me.

skin to accelerate. Gawd I love this car!)
