Tried out Wickes metal protecting black spray paint. Seemed quite good. Good coverage, good finish, etc etc. One small problem, there were a couple of areas that I wasn't quite happy about and found that if it's allowed to dry, you can't recoat. :( It wrinkles.
Any suggestions apart from stripping it all off and starting again ?

Funnily enough, Ive just had the same problem with POR15 paint! I had to weld on a couple of brackets on to my nicely painted chassis, so cleaned an area around the bracket, welded it on and then feathered down the surrounding paint, put on the under coat with out any problem, when I put on the top coat, the feathered edges all started to wrinkle up.  My solution was to let it all dry then put another thikish coat of paint on so it pooled with in the wrinkles, then when dry, rubed it down and painted again which seemed to cure the problem. I presume that it is the solvent in the paint that starts to lift a thin edge of the existing paint :-\ 

You can get barcoat that isolates the layer underneath, but I'd think it's just as easy to strip it off really. Only reason I can think for it reacting with itself is that the layer underneath was still gassing off despite appearing to be dry. Maybe.

When you feather the edges it can react as the paint under the skin is still curing. If you can sand it, then leave it 24 hours it should be ok. Or just bury it in more paint!

Sounds like the same stuff that Hammerite products are made from. If you read the instructions on their tin, you get a samll window for a retouch and after that you have to wait 6 WEEKS before applying another coat.

You beat me to it, I was going to say the same thing

Thanks guys. Yep seems to be similar to Hammerite smooth. :(
Should have read the can  ::)
