hi im wounering if can you put fiberglass on rusted oil pan or will it get too hot, the stuff i have is short strand reiforced fiberglass body filler. i no it sounds stupid to do and i no it wont last long, but my question is if it will get too hot. thanks

Is 200-220 degrees too hot?

We'll I'm not shure there is not any thing written on the fiberglass can so I was kinda hoping someone would no how how fiberglass gets before it catches fire, some one already used fire glass cloth/ resin and that dident burn but I thought maybe the stuff I have can't get as hot becuase it's called fiberglass body fill

Well.....the glass itself won't burn easily but the resin can burn.
Just slapping it on an oil pan --- there won't be enough heat to be near the ignition temperature but the resin might get hot enough to break down.

EDIT: You have a hot exhaust pipe under the pan too.

Looking in a boat forum I found this, discussion about fire damage to a fiberglass boat:
If there's evidence of fire damage to the glass itself, it's probably a bad idea. Above 60, 80, 100 Celsius, depending on resin, the resins that hold fibreglass together begin to rapidly decompose, leaving weak spots and bubbles in the laminate. The result is hard and looks fine, but will fail catastrophically under a sudden load.


Replace the oil pan?

yea it seems like people use resin alot on oil pans alot and nothing happen im just wondering if maybe the find a high temp resin. im not using resin im using- reinforced short strand fiberglass body filler

Well, that's even more different from real fiberglass.

More like just a step up from Bondo.
