FG Gauntlets problem

OK, i'm trying to reshape the bottom clamshell of my fiberglass gauntlets. They are a bit warped. I went and snagged a heat gun last night, heated the part that is warped up, shaped it to make it line up right and then ran cold water over it until it was cool again. 2 hours later it was back to it's warped shape. This is the first time I've ever worked with fiberglass. Am I doing something wrong? Any help would be appreciated.

Doug,

Did you tape both halves together during and after heating? That trick worked for me. I remember it took a couple of tries before it took. LMK what's up.

I did that last night when I tried again. I guess I'll see if it took when I get home this evening. If nothing else I may leave it taped together and heat it up again just for the sake of doing it to make sure it stays
