ab007:
I do not know if you can get it in the UK but here in the states we have a non toxic paint stripper called Citristrip (http://www.wmbarr.com/product.aspx?catid=36&prodid=63). This is really great and I have used it to strip polyurethane from my BVM Maverick and am now using it on a Viper I am refinishing. I apply it and it must sit for a few hours to a few days depending on what kind of paint you are stripping. If it is something like a rattle can paint then it will lift the paint off in about 6 hours. If stripping a catalyzed paint (auto paint) then I have applied multiple coats over a two day period. The nice thing about this stuff is that it is non toxic, does not affect fiberglass covered wings. I let it wrinkle the paint, then scrape off as much as I can with an old credit card. Clean the surface with water, let the surface dry for a day or so and then begin the sanding process. Here is a link to a couple of threads on the refinishing.
