Default filling pin holes

I'm just now putting epoxy on the bottom of the boat I'm building. Just wondering what everyone uses to fill those crazy little pin holes. I seem to have a over abundance of them when the epoxy dries. Thanks in advance for any replies.

The pin holes are caused by air bubbles when mixing the resin. Try this..... A little tip. Lightly pass over the resin with a Propane Torch to draw the bubbles out. Becareful not to over heat...

could stirring the resin slower cause less pin holes? if not, maybe get some autobody filler to fill them.

Stirring less aggressively will lessen the air bubbles.
Also laying out thinner layers and using a skread to work the resin will work most of that out also.
And as Andy stated, a properly used torch will get rid of those for you.

Another little trick/tip :
When mixing the resin together , warm the resin under your hot water tap and get it warmed up . This way , there is no worries about the torch , or anything else . The resin will get looser , which , in turn will allow the bubbles to flow to the top and wha-la ... no pin holes .
I use marine 2 part epoxy which is VERY thick and this cures that problem ALL the time .

I got this tip from Phil Thomas of RC Marine Designs who builds epoxy-glas hulls. Use ordinary wall spackling thinned slightly to fill the pinholes. You want it thinned to the consistancy of mayonaise.

I would use litweight body filler (Bondo) I think it would be better to paint over than spackle.
