your not when its base coat but you should just about get away with it try a test piece, the celly was never designed to be over coated with clear so you are supposed to apply it as a top coat, and the fact you are using 2 different products only complicates the process even more as your clear is still soft 2 weeks later
I think you are right there mate it must be the thinners leetching out the celly keeping the clear soft, I guess it will eventually go hard. I hope
What grade would you give the final celly coat a light rub with 800? wet
