Tenacious Baits

Thanks for the tips! I'll give them a try and let you guys know how it goes.

Yes, it's an open pour mold and I start at the tail.

I just heated and washed the rtv molds within the past week. I was having the problem prior to that.

I've been pouring swimbaits and have been able to get rid of almost all my bubbles. I get a lot of small bubbles in the tail portion. I'm using an rtv mold and mf plastic. I do not have bubbles in my plastic before I pour. I don't get bubbles in any other parts of the bait. I heated my molds in the oven for an hour to sweat out the oils. Washed with soap and water. I keep them in an airtight container in my house. I need help getting the small bubbles out of the tail. Any suggestions?
