				Heat bubbles
			 
 I built several plugs over the winter and never had a problem with them.  I was surprised they even worked.  I put several in plug box and left them in my backpack in the sun.  When I looked at them last night I noticed bubbles in the all the plugs, even a couple I hadn't used.  The rest of the batch in the basement is fine.  Could the heat in the box lifted the paint?  I used Minwax Wood Hardener, kilz Rattles (Painters Touch) and Poly.  Any ideas? |
