Then I sprayed the top coat of blue and started to get a reaction that looked like this


I had no indication on the previous coats of primer that anything may be wrong, all the 2 pack paint was purchased at the same supplier to make sure it was compatible - when I peeled off the paint it went right back to the bare metal so I can only assume I hadn't cleaned the metal well enough before putting on the etch primer
The next stage was to sand down the paint where it had reacted and mask up the paint that looked OK



Next was to put on the primer again after making sure all the panels were completely cleaned



I will attack the top coat again when I have enough time to do it and keep my fingers crossed that this time I have got it right or you will probably hear the screaming and swearing!!!
