As I said, there is no Simple green, Pine-sol or Dettol where I live. That Dawn power dissolver sounds very much like a product called "Drano Power" which is basically Natrium-Hydroxide, 'might work, but I had little success with it when stripping regular plastic models (styrene). The plastic of the models suffered no harm, but neither did the paint (3 layers with base-coat in-between.... dam you ebay...). I had to use my killer mix of diesel, alcohol and hydroxide. (no harm to the plastic if you don't leave the minis in the stuff and wash it off after you're done, btw.) But this mix will probably kill resin, 'should really give it a try with some resin sprue.
Does this Fairy Power Spray smell like ammonia? Is that an oven cleaner? Because it is not available here either :excruciating:.
You are in a bit of a fix. Shoot, even if I offered to ship some stuff to you, it would take forever to get there. lol!
First, are you stripping acrylics? Enamel and even oil paints will come off with the Dawn Power Dissolver but it takes awhile. For the horses, I soak the inside of one of those storage bags (it's a trigger spray) and then spray the resin. I put it in the bag and seal it. I lay it on it's side and let it go 20-30 minutes and check it.
Depending on how much color if any is coming off on the bag I'll either flip it over and it starts all over again or take it to the sink and scrub it off with a tooth brush, mild dish soap and luke warm water (you don't want hot, hot water with a resin).
The last resin horse I stripped was done in less than an hour. The worst I heard was someone took a full week to get oil paint off of a resin.
I've used this method on both resin sculpts and mass market Breyer horses that have been customized. They Breyers are cellulose acetate plastic and it works just fine on them too - but again it depends on the sealer and paint. Any epoxy or Apoxie on there will come off most likely. But maybe that Drano Power might work if you give it a week and seal it up in the plastic bag.
Other than that the only other paint stripper safe for plastic and resin that I know of is Chameleon but I don't know if they are still in business or if you can even get it where you're at.
I have heard of acetone eating resin so if you go that route you want to be careful.
ETA: The Dawn Power Dissolver label says it contains biodegradable alkaline cleaning agents and solvents. Contains no phosphates.
Well, that tells us a whole lot...sheesh! lol!
