Boom Mat
« on: February 21, 2023, 07:01:22 PM »
Thinking of using the spray-on Boom Mat on the underside of my hood.  Comments?  Anyone ever done this?

I would suggest the oe style insulation or nothing.

I bought an OE style type and a mouse decided that it would make great bedding material from the back of the mat and there were a lot of acorn shells between the hood and mat.  Going to have to take the mat out and buy an new one as it has holes in it and is tearing apart.  Wasn't crazy about this mat anyway.

Well, from everything I have read, there should be something to protect the hood paint from getting so hot and damaging the paint.  It is just a thought but open to other suggestions.  Maybe the heat mat like you put on floors only for the hood?

Honestly, I have never seen paint affected by underhood heat (except Vipers) and I have always removed the insulation from every vehicle I've owned. I think your chasing a problem that doesn't exist.  Anyway, a solution could be a high ceramics paint or a foil type mat on the underside to reflect the heat back down.

ok, thanks.  I just thought it was there originally for a reason so it needed to go back.  Maybe I will just use some paint that can take the heat and spray the whole underside black.....so it is a consistent color.

Older paint jobs and bad paint jobs do suffer from the heat.  I've seen a few with cracking paint.
I did the factory style just because the under side of the hood is so ugly.  Boom mat and dyna mat type things would be way overkill and weigh too much.

I have read that the primary purpose for underhood mat is fire suppression. They are generally made out of charcoal impregnated fiberglass, with the idea being a fire under hood melts the plastic retainers and the mat drops to help smother the fire. Never looked into it much but makes sense.
