I had a customer bring in a 20" catfish. I was going to rder an artificial cast fish from McKenzie but I thought I'd try this 1st. Let me know your thoughts. I carved a catfish with the original measurements out of the dense carving foam, minus fins and tail. I cut slots for the fins and tail. And carved features such as gills, lips, etc. Looks very good so far. I have just poured envirotex over the entire body (as a sealer). Has anyone done this? After its dry, I will paint and seal again with clear. I could not find catfish fins by suppliers, so I ordered a set of redfish fins. (they are similar, but dorsal fin needs to be trimmed and becomes an anal fin and I am building an anapose type fin.
