Hi! So I'm designing a part that has to go over an exhaust of a car (not too near but not too far either) so it's got constant hot air blowing over it. I've been using pre-preg carbon fiber for the part and I was wondering if I could coat it with this:

which I came across while browsing the internet. Was wondering what you guys would think of this if I used it as my surface gel coat for my pre-preg parts.

Thank you!
