Yahshu Posted April 28, 2019 Share Posted April 28, 2019 Has anyone had to strip Alclad, if so what process please. I'm in Oz & we have no purple pond here that I'm aware of. Quote Link to comment Share on other sites More sharing options...

Tom Geiger Posted April 28, 2019 Share Posted April 28, 2019 You are correct, there is no Purple Pond in Australia! An Aussie friend of mine inquired of Castrol locally and was told that they couldn't sell the chemical make up of it in your market! Quote Link to comment Share on other sites More sharing options...

Rider Posted April 29, 2019 Share Posted April 29, 2019 Ammonia is 10x cheaper then ISO. Just offering another option. ISO is a good option if you use acrylic paints, but expensive as a stripper. Brake fluid or Heavy Duty Oven cleaner work great too. Just as a bit of side info. I have left every type of part in both solutions for months with no effect, clear and coloured lens as well.

peteski Posted April 29, 2019 Share Posted April 29, 2019 Brake Fluid (polyglycol-ether-based) can craze, or soften some polystyrene and urethane resins. Be careful! Oven cleaners which are lye-based (Sodium Hydroxide) are also good at stripping paint (and skin from your fingers). But again, careful when using on urethane resins. The Purple stuff also contains Lye (and that is likely the main ingredient in it which strips the model paint). Isopropyl (ISO) alcohol (the strongest solution you can find - preferably 91% or higher) can also strip paint and not affect polystyrene, but might require some elbow-grease (like scrubbing with a stiff brush, or rubbing the surface with a rag) to get the paint off. Again, be careful when using on urethane bodies. Quote Link to comment Share on other sites More sharing options...

I can't say what it will do to resin or urethane resin because I've never used it on that material, however, I can, from vast experience, say that it works very well on styrene plastic.
