I buffed this aftermarket rear wing last week with my orbital Flex. I really took care of generating no heat because i knew these plastic parts could react to heat. The passes were very fast (~10-15cm per second) without any pressure. The paint was still ice cold after each step:

- M105 on purple wool pad

- SIP on whipe pad

- PO106FA on black pad



Everything was perfect after the job but apparently, the day after, these bubbles appeared. How could this happen?



The body shop accepted to repaint it for free because it was a crappy job, but still... I'm wondering how could these steps generate such bubbles 24 hours later.
 
Did you give the paint time to cure before polishing it? From what I understand, paint needs time to cure and gas out. I just had my truck painted and I waited at least 45 days before even washing the panel that was just painted. Hopefully the pros will chime in and give you more insight then I could.
 
Fiberglass?



If so, these need to be thoroughly cleaned to remove whatever mold

release agent used. And being some what porous, it's not always easy

to do (efficiently for a shop).. It needs to be completely stripped and

gone over to check for tiny air pocket; which needs to be poked out,

and cleaned as it will hold solvent/release agent/contaminants.

From here, the entire piece *should be epoxy primed to begin:

filler work to smooth it out and/or urethane primed to get it ready

basecoat/clear coat.



Plastic/urethane wing?



Poor prep... Still needs to be stripped down.
 
sounds like it was recently painted? if so it looks like the painter didnt give the base coat enough flash time to let solvents evaporate before added the clear.
