I once bought a minor that had a vinyl roof fitted. I decided to remove it as it was lifting in places, then discovered the paint was in a bit of a state (plus rust/glue etc). I started with Nitromors - used 1 tin and really was getting nowhere, so I used my oxy acetylene torch with a lazy ish flame and just burned it off. Obviously you have to be careful you don't overheat anything, and finish it off with a DA sander, or a brass wire cup brush in an angle grinder.
It took me a while to do this, but just tackle a bit at a time, and do something else when you get bored.
I'll have to decide between this approach and blasting for my MM project.
If the paint stripper is old then it will hardly work, nitromors is expensive and not the best, I'd try your local bodyshop/ motor paint supplier who will be able to sell you 5 litres of excellent stripper.This will cost about £40. You should scratch the paint surface with a sharp knife or screwdriver, go all of the way through the paint to the metal, brush on the stripper and leave for about 10 mins, with good stuff you will find it strips down to either the steel or the red oxide primer of the original. As Pete says you may need to D/A the metal surface to clear off the stubborn bits. Wipe the excess stripper of with a damp cloth before you D/D though, and when fully stripped check the folds/joins of any panelwork to be sure you have removed all traces of the stripper.
I'll look on tuesday to see if there is a brand name on the stuff we use
Hope this helps
Funny thing is when vandals use brake fluid on your car it really does strip paint. Try it yourself and it's 'not very good' didn't think cr*p would be edited!!!
One of life's mysteries.
There is a 3M product that looks like a brillo pad that you stick in your drill or onto your grinder. Strips paint very quick Works well on knuckles too
Only down side is that sharp edges will destroy it, so we use it on the big flat surfaces, and the reliable wire brush for the tricky bits.
the 3M product is described as Clean and Strip on the Frost website. They are effective, especially the angle grinder version, but don't last very long and so are relatively expensive.
