I was wondering what do you use to sand between coats of e-tex? Sandpaper, tack cloth etc? I am putting at least 2 coats of e-tex on my cranks and jerkbaits now. Just curious what everyone uses.

No need to sand unless you are smoothing rough spots. The second coat will bond to the first coat. They recommend wiping with alcohol though. I used a rasp where necessary.

This is what I hear from rodmakers who consulted epoxy companies regarding multiple epoxy coats on rod guides and preparing reel seats for installation: No need to sand between epoxy coats. If you recoat within a day or so, it chemically bonds into a single mass that completely cures in 4-7 days. Using a solvent cleaner between coats may actually hinder the bond. For crankbait lips, it's best to sand the polycarbonate or circuit board lip to give the epoxy more bond area, then just blow off the dust and install it.

I don't think it is so necessary, but I do sand down the high spots. If two or more coats will be added, I'll sand with 120 grit sandpaper. Be careful not to sand so deep that you damage what is below the epoxy - like the coat of paint or lure body. Before a final coat, I'll use a finer grit like 400.
