Paint bubble

I have a paint bubble that keeps
Coming back on my dino 246 gts.

Same spot three times over 15 yrs.
Where roof and rear quarter panel
meet. Kind of a sharp edge.

Anyway to glue this down ?. Paint is flawless on the car otherwise

 

Find the cause and fix it right (down to metal) or ignore it. You can't glue it. Bummer you will end up painting more of the car than you want.

 

Ditto. Can't glue it. Paint "bubbles" sometimes have rust hiding underneath.

 

I’ve got a little one on the rear buttress a little bit bigger than a pin head.

Car was in the body shop last month for a bit of work elsewhere and I asked about it. They suspected a bit of rust as the most likely cause. Only problem, to correct it means respraying about 1/2 the rear end!! So I’m going to live with it!

Good luck with whatever you do.

 

Any pictures Sal?

 

Re-paint is the best and most permament solution.

 

I suspect you might be able to differentiate whether the paint has just lifted or if it is due to underlying rust by using a paint thickness gauge. They are a pretty handy tool to have generally. I haven't tried this one, so I don't know how well it works, but seems like a cheap investment to learn more about what is happening -> https://www.amazon.com/Thickness-Detector-Measurement-Crash-Test-Resistant/dp/B01H1PVMSA/ref=sr_1_3?ie=UTF8&qid=1520428011&sr=8-3&keywords=paint+thickness+gauge

If the thickness measures the same with the bubble pushed against the body, then it may be just that the paint has lifted. If it measures much different (I would guess "thicker", since rusted metal is presumably less attracted to magnets) then it seems more likely there is rust underneath. Of course, if there is old glue under from previous gluing attempts, it might also measure thicker. If it turns out to be rust, I would definitely have every bit removed and have that section repainted because it will only get worse.

 

It is very frustrating when one pays
Top dollar for these high end body
shops only to have the same problem again. It looks like the paint
Just detached from the metal.
I was assured it was sanded down
to metal and there was no rust.
I will post a photo tomorrow

Beautiful car by the way. Unfortunately, the only real way to sort is to repaint, and on a ferrari, most likely that’s the full works.

I had a scglietti a few years back, and some small bubbles appeared on the front valance. It was caused by the forming of the aluminium, where someone used the wrong hammer, which had picked up tiny bits of other metal, and then hammered out the finish on the valance. Those filings rusted while the aluminium clearly didn’t, hence the small bubbles. The only way to deal with it was a rub down and cleanse of the metal, and repaint. Looked great afterwards mind you, but ferrari paid for the work, which always makes it look better
