Default paint blisters

guys,a quick question, I have some paint blisters, no delamination just the paint, what would be the best method to get them down again, injecting some low viscosity epoxy and clamp down?
(I am a flyer not a builder, but for repairs I did use the west epoxy system, but that is rather high viscus)

regards

wolf.

I would think that that depends on the type of paint used. Since the paint, in effect sits on top of the structure (with some chemical/physical bonding) there is obviously some sort of contamination below the blister, or some other gremlin that caused it to detach.

IMNSHO, the best thing to do would be to sand the blister off (or cut it), sand a margin around the surgery site, feathering in the edge, clean the underparts well (first sand), shoot a little primer, then paint the defect. You might want to talk to a local automobile paint shop or supplier to get better info.

If the paint is urethane or has a clear coat, it makes repair harder.

I would suggest against injecting epoxy.

Wolf,
Stick a needle in the blister and see if there is any liquid coming out, and if there is a smell to it? How old is the plane?

Pictures? Age of the airplane? Some of the old primers were not good. It might get worse and need a strip and refinish.

The craft is 26years and 100h flight old, of but spend all its' live in a hangar.
the blisters are mostly on the side of the fuselage.
For liquid or smell the plane is a major and vaccinated and assured me she always was using protection, but she spend a lot of time in a dark hangar with other aircraft, and you never know
