spray paint question: Why does clear coat wrinkle some finishes?
I am painting the rest of my race bike. I painted (with rustoleum) the tail end section of my bike last week.
Today I went to clear coat it (krylon clear coat). The majority of the piece came out ok, but one side got completely wrinkled. I dont understand how this happened.
Was the paint not fully cured?
Back to sanding and painting now I guess. But I dont think I'm going to clearcoat this section anymore in the future. For some reason, this ONE piece of the bike is prone to wrinkling (post clear coating). I dont know why. The rest of the bike is fine with the clear coat.
Thanks for any suggestions
Lets take a step back here for a second.
Are the fairings on your bike race plastics? like sharkskinz...or are they OEM?
How well did you clean them...I.E soap and water then solvent clean scuff/sand and repeat?
Do you have any pics of the wrinkling?
Is this happening on the whole fairing or just part of it?
If one of the fairings is a diferent material that can be a culprit for lifting, some materials outgas heavily and the minute you try and seal them with clear you could run into problems. IMO
I ran into a lifting problem while painting my gsxr but that was a solvent issue due to temp and primer that decided it needed longer to dry.
for the fairings on the bike. do you need to use a flex additive??
If the rustoleum is enamel and the krylon is lacquer then that's your problem.
