I have a 914 with fiberglass flairs. A the top of each flair near the seam the paint is bubbling. A complete re paint is not in the cards. Does anybody have experience with such a problem? Thanks

There's no mystery. Rust and corrosion makes the paint bubble up.

My 40year old seams do this as well. I sand down to the rust, clean it up and use paint matched rattle cans to touch it up. It isn't pretty (fine at 20feet) and often it bubbles again, but that's all you can do short of actually fixing the seam and stopping moisture intrusion. No point in giving it a real paint job unless you fix the underlying issue.

Another potential source of bubbling is excessive solvent that gets trapped in filler and/or under too much paint that flash dried too quickly. Sometimes called “solvent pop”. Solvent pop would be more common on a very fresh paint job. Could also have been from poor prep prior to paint and related to adhesion problems. Really too many possible causes. None of them are easy to fix. |

fiberglass to metal bonding is always "sketchy" at least. Bonding two dissimilar services is asking for it. Leave as is and save your money and install steel flares
