Problems painting skirts

[djyo]

Im trying to paint some skirts for my astra, i sanded it all down, panel wiped them then used normal primer.
After 5 minutes it will react and cause lots of cracks in the paint so i thought it was the primer.

Sanded them all down again panel wiped them then used plastic primer but same thing happend!

It did look like the cracks might be because of deep scratches so i sanded all those scrathes out, penl wipes then plastic primerd them again but same thing has happend lots of cracks??

Anyone know what im doing wrong? never had a problem like this before

Looks like you are trying to put the paint on too thick. Also is it cold where you are painting?

That's the paint underneath reactivating and going soft. You'd be best off sanding them down to the primer.

chees folks i always thouht aslong as it had a good key the old paint was fine left on. Il sand it all back for the fourth time lol and see what happens

You'll normally see that kinda thing if you paint 2pac over rattle can paint. As the thinners in the 2pac reactivates the paint underneath.
