: unless you have a pin hole like I did, then it will blow a nice round bubble

I had the blowing bubbles routine happen to me. I had done a seal coat and the glass had been applied and was cured. I thought I was past the stage where I had to worry about outgassing. Wanting to reduce time spent on fill coats I figured I'd warm her up a bit to cure the epoxy more quickly. When I entered the workshop a while later I was greeted by 3 large bubbles. I turned off the heat but the bubbles didn't dissapear completely. All evidence of the bubbles was easily sanded off but...
Will I have to do anything special to ensure that these pinholes are completely sealed by my last fill coats or varnish??
Like heating the boat before my last fill coat and letting it cool as I apply the final fillcoat to draw the epoxy into the pinholes.

Thanks,

Ken
