Well a good stripper is a heat gun (a lot hotter than a Monocote gun tho') or Bix---which I have used to strip a lot of paint in my day. Not from models, but from woodwork. I think you will need aggressive stuff like that to remove Rustoleum-like paint. You can find BIX at your hardware store. It contains lots of good hot chemicals,---acetone, methanol, and the best of all, methylene chloride. The latter is what makes a gallon of this stuff weigh so much. Anyway you would need to use it outdoors. I think it is also sold by the quart. You slop it on and let it soften the paint. Then you can scape it off. The trick in scraping it off is not damaging the soft balsa. Maybe you are stuck with sanding.
And by the way, a spell checker doesn't help if the words are real words! Like two, too, and to, led and lead, their and there......
