Nooooooooooooooooo on the epoxy! Epoxy starts to lose its integrity above 90ish degrees celcius (whatever that works out in your system, its lower than 225F though!).<br />

I've done alot of fibreglass/carbon fibre work with epoxies and have found this out the hard way, rendering a rather intricate R/C boat hull I made out of carbon useless as the radiant heat from the motor was enough to start effecting the resins in the matt. It re-hardens once the temperature cools, but when exposed to heat most…

You can get epoxies that will handle prolonged heat (as I found when I started doing race car parts), but you need seriously deep pockets to get them. They start at around 3x the price of normal epoxies :( It's a bit pricey but I think…tag:kregjig.ning.com,2010-12-05:2900167:Comment:779912010-12-05T17:46:28.936ZJohn Schabenhttps://kregjig.ning.com/profile/JohnSchaben
