I would, but I got the foam board for free
so I'm gonna use it now until i get some rigid blocking material. I'm gonna use the foam board because tape and water don't last as long as foam and water. Might as well use it since I got it for free. I'm not gonna use any of it for underbelly stuff tho since it is very liable to catch on fire :O. Until I get some coroplast, this is all I have to work with, right now there's a hole in my grille block, which I think someone at my school kicked in because they thought i'd be funny. Nothing more duct tape can't fix
. I want to hold it on there with something not permanent, but more resistant to water than duct tape.
