Hot engine bubbled paint?
I have a small bubble in my new paint and the paint shop told me it is because my engine is too hot.
I agree that my motor and headers run hot, but so do a lot of Vette's.
Would this cause a bubble or are they just looking for excuses?
I have some Reflect-A-Cool, constructed of fiberglass material backed with a layer of aluminized reflective foil to handle direct continuous temperature of 400°F and was thinking of sticking it under the hood.
I am fighting for them to strip and re-paint at the mo
ment.

It is smaller than half a penny and under the motion stripe on the driver side right above the valve cover.
Stock insulation no longer fit with this motor, so I guess the Reflect a cool will be used.
Note the stinger was added by me and it was glassed in and allows the engine to breath better.

I have seen top fuel drag cars that run way hotter with fiberglass bodies and the paint does not bubble.
Thanks

Lets hope it does not bubble this time, but I might also wrap my exhaust to keep heat in.
I am still curious to how hot you can get paint on fiberglass before you get problems.
Thanks

My 'opinion' is that the paint folks used some sort of volatile cleaner/prep fluid prior to paint and that some of it stayed in the glass. That stuff has to be purged by heat before painting or what you are seeing will be the result. Putting an insulating blanket under the hood is probably a good idea, because more of the same could occur.

Thats exactly what it sounds like.

I agree with the prep problem. I had the same thing on my 68 and it wasn't on the hood. It would only happen on hot days when the car was in the sun(black car), and would shrink back down to unnoticeable once it was back in the garage and cool. If it was engine heat, 1/3 of your hood would bubble, not just one tiny spot.

Kool that the shop is standing behind their work . I tend to agree on the fact that if engine heat caused it ; a lot bigger area would be affected. Some of the new "thin " high tech insulation might be a good idea . I have a set of Chrome Hooker sidepipe headers on my '74 L82
and the radiant heat is no problem except for me when trying to mess with stuff before the engine cools. You just got to be real
careful routing plug wires !!! I do not agree with wrap for headers
as I have heard it can create problems under the wrap by confining
the heat instead of it dispensing normally.
And also that stinger in the middle of your hood looks really ,
really nasty!!!! Good job !!! Love your car.

I recently purchase a thin insulating product called "Lava Mat". It works great, AND it is a dark carbon fiber in color as opposed to the foil look. I'll warn that it IS expensive, but... here is the webpage:

Do you know if it sticks well under the hood and what the cost is for the product?
Also a picture of the underside of your hood would be great
(with the Lava Mat)
I figure if it sticks well and looks good I will buy one of the following:
770003
Lava Mat™; 36" x 48" with adhesive
770005
Lava Mat™; 60" x 48"; with adhesive
I do not like the silver look under the hood as much as this look.

There is a link on the webpage I originally posted for PACE. That is where I bought mine. They shipped promptly and no problems. I used it to isolate the starter and solenoid. However, it has a very good adhesive (I'm sure it is same as used on Dynamat and other similar products). I can't imagine it would be a problem on the underside of the hood. As I said, it is very pricey. If I recall, the 4'x6' piece is around $150. !!!

The 3M 80 spray glue is not sold in Canada so I need to find a replacement or drive across the border to get it.
This post talks about it but no one really says how much heat it cuts down or how well it sticks after a few years.http://forums.corvetteforum.com/c3-g...post1575820111
I would hate it to drop on the engine while driving a few years down the line and catch fire.
