Hi, Ernie. Haven't visited this post in a while and didn't realize you posed a question to me. Re. the CA debonders vs. Acetone...
MOST of the commercially available CA Debonders use Acetone as their base, EXCEPT "Ultra Super Solvent" . "Ultra Super Solvent" is a Nitromethane based formula(I believe its 95-97% Nitro) plus denatured alcohol. This is why I believe it is so good, it WILL debond anything!

Re. Nail Polish remover: It will work, but not as well as straight Acetone. You see, most Nail Polish removers are mixed with Isopropyl Alcohol plus a fragrance or emollient; and because of this they don't cut the CA as fast, or as completely.

IMHO the very BEST CA debonder is "Ultra Super Solvent" from Golden West (also brought us the original CA's - "Hot Stuff").
So, Ernie and others, PLEASE pick up a bottle of this from Omni Models, you will be amazed at how great it works, and how versatile in use it really is...
