I like the black 3/8" epoxy brushes. They run about .20 each or about $16 for a box of 144 which is what I buy at a local hobby shop. I use the BSI 30 minute slow cure and also clear two baits at a time and then toss the brush. Soome guys clean their brushes. I've thinned it with 2-3 drops of denatured alcohol. You will get enough time to do a 3rd bait but I am not happy with the results. It goes on thinner but also dries thinner. I use to the those acid brushes from harbor freights but the quality it poor and they vary too much from batch to batch. This is what I've found that works for me today..........but that could all change tomorrow!
