Help! What the Feck has caused this on my mudguard!!!!!!!!!!!!!!!!!!!

in pics 3 + 4 you can see how on the top its started and then spread over a few minutes...... its as if the peral has somehow bonded to the base coat and then the combined layers just expanded and lifted off the primer..... I pressed it and just went flat...... after a few mins I pushed the raised bits and it just split and I could easlily just peel it awa y to leave just the primer..... see last picture!

WHY??????

what type of primer did you use? because it looks like its not compatable .was the pearl polyester base ? what type of lacquer ?

Its a 2 pack primer......... no lacquer yet.

its not done this on any other panel though!

the mudguard is fibreglass...... but so are side panels so its not that!

Its only on the mudguard!

did you put two coats of primer on???

Is it possible that the primer hadn't gone off fully before the pearl went on?

Rich... yes 2 coats of primer

coaster...... i guess it could be possible - it was sprayed the day before...... had sat by a heater, but possibly not fully cured?

i have had this happen to me ........(as you think) i think that maybe the second coat went on after the first had started to go off and has not bonded together so the top coat then softens the primer again causing a de laminate effect

at least its just a mudguard and not a fiesta that i was spraying

That looks very shiny for basecoat with no lacquer. Are you mixing systems ?

Nice colour by the way.

The base coat is the matt green... then a second coat of pearl metallic lear,.... which is what caused this reaction.... pics were within 5 mins of spraying so was still wet
