I just repainted a rod with Testor's Model Master Metallic Spray Enamel. I let it cure at room temperature for about 72 hrs. Then coated with Permagloss. The permagloss softened the paint and actually removed some in a couple places.
I have used permagloss on a couple fo other rods but put it over the old finish and did not have the problem with softening the finish.
My question is how long do I need to let the new paint cure before applying the permagloss? Do I need to change to another type of paint.?

I don't think you'll know that without some testing. I might not try putting P-Gloss on there until it has cured a week. Even then it should be on a scrap of blank or something similar. Some paints you might not ever be able to put it over. Some clear rod finishes may stand the hot solvents in P-Gloss better than paint. Chances are the rod finishes you have put it on were not new. Some of the spray can auto finishes are designed to be used with a clear coat. That might give you the look you want but may not be a durable as the PermaGloss

Enamel takes a long time to really cure to a hard surface.
The best thing I have used is any auto finishes like DuPliColor. They dry fast and can be coated - working fast - I let them sit overnight.

With any enamel at least 1 month, I have had some repaints that sat 6 months even then PermaGloss can and does soften or crinkle's the enamel. Enamel is not the stuff to use on rods doesn't flex very well ether.

Perma gloss is a hot Urethane. By that I mean the driers used to cure the Urethane are called hot, this has to do with the cure time. In the auto paint industry . They have slow, medium or fast driers. These are use in conjunction with how hot and humid the outside weather is like. So if Perma gloss is placed over a freshly painted rod the paint well lift.

I have never had good results with PG over paint of any kind.

DupliColor paint (overnight dry), followed by Duplicolor clear coat as a sacrificial protectant (overnight dry).....then use PG....the PG likely softens and may damage clear coat, but in every instance I have done this, the actual paint is perfectly fine and any damage to the sacrificial clear coat is invisible.

From what I understand Permagloss uses a product called Zileen (spelling??) to thin it. I attempted something similar and had the same problem when I called the company they told me that they have not found anyting that it would not eat off or soften. They told me if I find something to let them know. For what it is worth.

Back To ya BOB,

Thanks I need it!!!
