Alclad Help

I have been using alclad for years with no problems. Lately however when I apply chrome or any polished finish it will rub off with any amount of handling.I never had this happen before,and this is over a black enamel base.I am probably not letting the enamel cure completely as Im waiting about a day,could that be it?Any thoughts or suggestions would be great.

i would wait a little bit longer for the paint to dry and fully cure, enamel takes very long to cure.

Yes, let the enamel dry longer. I have been able to shoot Alclad right over Testors enamel gloss black within 15 minuts, but the enamel still takes a week or so to fully cure under the chrome.
It just makes for one shot painting so to speak, I don't think there is any benefit other than that.
Also, build up the Alclad in very thin coats, between 3 and 6 very light coats. It seems to dry harder for me that way.
No matter what, it still must be treated with extra care compared to other paints... - Mark

I've had metal type paints rub off before.. It was due to not waiting long enough for it to dry.. As mentioned, enamals take a long long time to cure.. I was using humbrol enamel metal cote, so I think it might be your base coat of enamal..

Enamels are good, well for brush painting, it's just the length of time they take to dry..

I do apply the alclad in thin coats,and it looks chrome as it should.Its just that I have old parts that I painted, lets say a year ago and I handled them a lot with no rubbing off.I guess the only difference could be letting the enamel dry longer,because the alclad obviously dries in minutes.

So far I've only used Alclad Chrome on some test pieces (an old kit whose enamel paint was applied over ten years back) and yes I found that although the finish was excellent it did wear off with only light handling.

BTW, I've been told that Humbrol enamel will dry a lot faster if the the enamel thinner is cut 50/50 with cellulose thinner...not tried it myself though.
