Well, I'm making a shotgun, in case you didn't already figure that out.
I pepped the entire thing the other day, except I left a few spots open so I could strengthen them later on.
Anyway, I decided to fill the entire gun with "Great Stuff" spray foam insulation. It's basically an expanding foam that hardens into a rigid...thing. It would out much better than I expected. The gun is very solid, much stronger than if I had fiberglassed it. It will definately keep it's shape during the resin/bondo process. I probably should have resined the outside first, to help it keep it's shape if the foam expanded to much, but it worked out fine anyway. I highly reccomend this to anyone else looking to strengthen their weapons.
I hope to put on a few coats of resin tomorrow, as long as it doesn't snow. Then I'll paint it after I finish pepping my EOD armor.
This is when the curing process is about 1/3 done. I put too much foam in, so it's sort of expanding and pushing through all the holes I left open. No big deal, I'll just cut off the excess foam.
Yeah, you see what I mean about how much it expands. That gun was packed REALLY tight with the foam. Good thing I did a good job pepping it, or it would been ripped apart.
Gives you kinda a size comparison...yeah, not really.
I plan on putting a flashlight in the gun later, this is the one I'm using. You can also see how much the trigger guard filled up. It got kind of balloonish, but I fixed it since I took this pic.
Yeah, the light again.
Here's a few more pics of it once it finished curing. I think these do it a bit more justice.
Please give me feedback on how I can improve and whatnot. I'll update with some pics of the gun with all the little pieces attached when I get to it.
