Suggestions For Adhesive-Backed Heat Insulation For Underside of Hood

I used the fatmat rattle trap *** for mine, rolled on easy and covered all of it even the braces. Can take a pic if you want, alot cheaper then the boom mat I think, I covered pretty much the whole inside with this stuff and inside the door panels outer door skins.
I would like to see pics if you don`t mind.
Thanks Mike
