Why does the primer keep doing this? Have sanded back and sprayed 3 times now, and everytime it cracks.
Seemed ok when I sprayed it with normal primer, but you could obviously still see the dips in the paint. So then tried spraying filler primer over normal primer and it still cracked!
The silver is the colour it used to be, never got it fitted to the car though as the finish was crap. The paint is so hard in places though is impossible to sand it back to bare plastic and the bits that can be sanded back then end up reacting with the rubber layer
Any tips would be nice
It had also cracked on the sides in a couple of places, but after sanding, using normal primer, and then filler primer, it hasn't cracked again. Its just the top section that now keeps cracking round the MFD
