Neil, I have always used Klean Strip Low Odor Aircraft Remover. I've tried others, but this works the best. A rule of thumb is to apply it in one direction and don't go over areas twice. This is suppossed to harm the stirpping properties if you do. A disposable natural bristle brush to apply, hose off with water. On heavy paint, might have to treat more than once. Once the paint is stripped, I used a wire wheel on a side angle grinder to strip to bare metal, and this does not harm the texture of the doors and rear inside panels. Light primer as to not fill the texture and finish paint. Just what I have done and had great results. Mike
