lightweight body filler question..

Workin on the '66 I'm using some new lightweight body filler, "Ultra-Lite Plastic Filler" I think...when sanding, it is getting really, REALLY hot...too hot to touch almost....is this normal? The regular body filler I've used doesn't get that hot....I can't even hand sand this stuff.

maybe you sand hella fast and produce a lot of friction just a thought but probably wont help lol

ur puttin to much hardener in it sounds like. light weight filler doesnt take much harder. gota think tis a chemical reaciton when u mix the 2 parts together.

damn i heard about putting to much hardner in making it realy hot but not when sanding, are you using a power sander?

This was getting hot after it was cured and I was sanding...I did put a lil' too much in and it set-up on me faster then I wanted, but not enough to make it hot while putting it on.

Baha-
I was using a pneumatic DA and a hand flex-board, both got it really hot. I'll try again tomorrow after it has cured overnite to see if it still gets hot or not.

yea thats what it is man, like james said its a chemical reaction sometimes it just reacts out of no where, I was showing my roommate how to fiberglass and he didn't know about using to much hardner haha it was funny so he starts glassing and all of a sudden you hear AAAH AAAAH AAAH it burned his hand it got so hot.

haha i know i shouldnt laugh but that sounds funny as hell

I mean, it cooled down after I stopped sanding, I'd sand again and it'd get hot again. Maybe it is just a chemical reaction...i'll see how it behaves tomorrow.

thats called fricition big guy ur puttin to much pressure on it.

yeah, i failed physics...well, i never took it actually

I sanded on it yesterday, it still got hotter then the other stuff, but not nearly as hot as it was. Maybe I"m stronger then I think...lots of practice with the motion I guess.
