since my tyres were/are dangerously low i decided to get some new wheels.
they are not as nice i dont think but they have brand new tyres all round and i just needed to paint them black.
primed
1 coat of gloss black
so far so good but does anyone know why this cracking happens?
i just sand it back and recoat it and it seems to work ok, but its abit annoying so i just got to put the final coats on now and hopefully should be ready to pop on in the morning.

i believe that happens because it hasn't bonded with the layer underneth it.
maybe need to key the paint underneath up more, or scotch brite iirc?

i would say thats a reaction in the paint what did you use to clean the wheels after you sanded them and applied the primer

its a chemical reaction between the primer and what was ever on the wheel nothing to do with drying
