@Jim Kueneman uses more SPI product than anyone here, so he might be the go to guy. I have both versions of their W&G remover. I use the waterborne first and the solvent based second, per SPI recommendations. I haven't had a fish eye yet.....knock on wood! If you decide to try using alcohol, I'd try it on a scrap fender, door, or something you have laying around. I'd be more inclined to try denatured alcohol vs rubbing alcohol. Look on You Tube and watch some of the Paint Society videos. Bryan is a great painter and a good teacher!
