I cracked a new can of Garco moisture cured urethane and dipped a batch of lures in it last night. Here are my initial observations:
The Garco can be found on the internet for around $25, which is cheap. It's designed as a floor finish. Like DN, it is a very light amber color but it is slightly thicker than DN. It still dips OK but there's a bit more drip-off after dipping due to the viscosity..
Garco's initial drying time is much slower than DN; the lures are still just slightly tacky this morning after 14 hours of air drying. Not so tacky that you can't handle them, but tacky nonetheless, while in comparison DN is always bone dry and slick to the touch after 2-3 hours. Since MCU takes several days to cure and get really tough, I don't know yet whether this is a show stopper. I'll let the lures hang for several days to see if the tackiness goes away as it cures.
Garco is also less glossy than DN; I'd say 'satin' versus DN's 'high gloss'. That's a plus or a minus, just depending on your taste in topcoats.
If the Garco cures out hard and slick, I'll be satisfied and will continue using it. Will toss it if it doesn't. Will report back after a few days of curing.
