BEEMDUB Posted April 22, 2012 Report Share Posted April 22, 2012 So I'm workin on gettin my box as sealed as possible from the trunk and so far I have gorilla taped the front inside the cabin all off and made mdf panels that I placed in the trunk and put up against where the box meets the opening of the cabin and taped those off too...I want to use expanding foam now, but I'm stuck contemplating on how to do it..and then I came up with this idea...If I took a trash bag and pushed it into the space I want filled and then spray the great stuff into the trash bag wouldn't that theoretically make the trash bag conform to the trunk and seal it just like it would if the bag wasn't there? My thinking is that with the bag idea if I ever wanted to remove the foam alls id have to do is pull the bag out...and If you guys don't think the crazy bag idea will work then what should I do? I really don't want to stain and mess up shit with the foam...Also how should I fasten my box down? It sits on the false floor of the trunk...

Noobtastic14 Posted April 22, 2012 Report Share Posted April 22, 2012 Sounds solid to me try it and let us know how it goes. You can also get 2" blue painters tape and cover any area you don't want foam to stick. Keep us posted. -Drew Quote I am a United States Military Arts and Crafts Professional.

ChevyBoy95 Posted April 22, 2012 Report Share Posted April 22, 2012 just make sure the bag can conform the the shape, meaning weird turns mixed with sharp edges and a weak garbage bag could mean tears and foam where you dont want it. but as long as the bag is strong sounds like a solid idea.

skittlesRgood Posted April 22, 2012 Report Share Posted April 22, 2012 i tried this once a few years ago. the foam never hardened inside the bag. give it a shot, just do a test bag first and make sure it cures.

Skullz Posted April 22, 2012 Report Share Posted April 22, 2012 If i'm not mistaken that formula requires air to set and cure so once you place it in a bag it will stay in a somewhat liquid state, don't know if that's a good thing or not though.

SmallTruk Posted April 22, 2012 Report Share Posted April 22, 2012 I tried the same thing a few months ago and like it was mentioned the foam never cured. I'd use the tape method Quote Link to comment Share on other sites More sharing options...
Hotdog Posted April 22, 2012 Report Share Posted April 22, 2012 You might want to try Pool noodles and stuff them in there or use a bike tire put it in place and fill it with air for a nice tight fit.

andrew018018 Posted April 22, 2012 Report Share Posted April 22, 2012 Tried the same thing as well, it did eventually harden but it barely expanded to double the size of the can and took forever to dry. The spray-foam ideally needs moisture and plenty of air to work properly.
