Testors enamel primer question.....help!

I have been doing some searching and read where another fellow had a similiar prob.  I cleaned my parts while still on the sprue with 91% Alcohol but wiped and dried them very good I thought.....could the alcohol be the prob. as in this mans case?  I would have figured that primer would have been good to go within a few hours.

Hi flygilmore,

I've had exactiy that problem with their grey primer - the reason I don't use it anymore. I posted of my problems here a couple of years ago and got advice including to let it cure (dry?) for days to thin it with lacquer thinner. I let it set for a couple of days with no joy. Cleaned it all off with mineral spirits and tried thinning with lacquer thinner. It did dry 'completely' but after several hours. And, frankly, I still don't know what caused the problem. I had cleaned the sprues with soap, water then 70% isopropyl alcohol.  I've gone to all acrylics since (except for Alclad) and haven't had a problem. Wonder if your Primer could have come from the same batch as mine. BTW, I had used other Testors enamels and they are slower drying but within an hour or so - NOT days. Just my experience.

I just went ahead and ordered some fine surface primer from Tamiya for my next model.  The Testors is finally pretty much cured.
