So I went to start working on my Endor rifle to paint it. A few weeks back I made some little spring clamps to hold the parts while I painted them. Then I promptly forgot to remove one. So the part is all warped. I know you can use heat, but the Internet gives all kinds of contradicting opinions. The one that sounds like it might work for thicker parts like these is submerging it in hot or boiling water then gently bending it back to shape. I have a heat gun, but I think it only has "off" and "blow torch" settings, it's not variable temperature. Does the water thing sound like this will work or is there a better way. The pieces that are warped are maybe 1/8" thick if not a little less. I *think* if I can get it pliable enough I can use something flat to hold against it to flatten it back to shape.The top pic is what the part is.
