Alclad problem

[van883]

Having painted a mig 15 in humbrol gloss black (as I have done before), then left it to dry for several days, I sprayed a light coat of alclad on to find that small parts of the aircraft crazed and the paint softened and wrinkeld up as if I had put paint stripper on! Other parts of the kit were fine with the alclad drying very quickly.

What has gone wrong?

Exact same thing happened to me with a Tamiya 1:48 P-47...... but only in parts, not the whole airframe. Ended-up stripping the whole lot back to the plastic then starting again using Tamiya glossy black straight from the rattle-can.

My problem was probably temperature/humidity/condensation - it was probably too cold when I laid down the Alclad, there was nowt wrong with the undercoat. My proof of this is:- the enamel undercoat did work on a different project without any probs at all and I have had a couple of times when Alclad has 'reacted' with the undercoat - exactly as you describe - when it was too cold and/or damp to spray.

There could be other reasons, but this is my experience.

I have always had problems with alclad.  In the airbrush it clogs up faster than the toilets in a frat house on chili cheese dog night.  The only worse thing I have used is Testors automotive colors out of the rattle can in German silver.  Am I the only one with the same problem?

Thanks for the tips. I haven't really had problems with it before. My conclusion is that i sprayed it on too thick in a couple of places, which mented the enamel. Lightly misted on at low pressure seems to be what I need to do.
