Hello,

I was covering my Sig Somethin Extra with ultracote, and i covered one side in silver. Then I went to cover the bottom of it in silver, and when I took the gun to it, it looked like it was like bubbling up or something. I'm thinking it was the hot air maybe was trapped, and couldn't escape, so it just bubbled. Not sure. Any hints, tips, or ideas and how to resolve this problem would be great!!!

Thanks</p>
