You can spray thinned urethanes, including 2 part catalyzed auto clear coats. Good results but it requires protective equipment like a rated face mask and clothing, positive air supply, or a paint booth with power ventilation and a filter system because they can be quite toxic. You can dip baits in moisture cured polyurethane like Dick Nite (there are other brands) or in one part auto clear coats and hang them to drip/dry. Again, good results and simple but moisture cured coatings need careful storage to keep them from hardening after exposure to ambient air moisture. All said and done, many builders like epoxy because it stores easily, is brushed on, and cures to a very smooth durable topcoat. The downside is epoxy needs to be rotated after application until it hardens to a state where it won't drip or sag. The simplest epoxy is probably Devcon Two Ton because it makes a thick coati in one application and cures to a sag-fee state in about 45 minutes at 70 degrees temp, faster than other epoxies (you can't use quick cure epoxies like "5 minute varieties"). Some paint companies are now coming out with durable water-based clear coats for a less toxic solution (auto painting and the EPA drive development in this area). Some like them, others report unfavorable results so I think a lot of use are in the "wait and see" or experimental mode on them. That's a snapshot of the waterfront.
