Default Re: Sealing Techniques?

I read an excellent water penetration study a long time ago, that compared alot of different sealing methods, with variations of dipping vs spraying, cut or uncut, amount of time in water etc. My personal favorite method has given me tremendous results over the past few years.

I use rebar wire to hang and handle the plugs. Can be found in the masonry and concrete sections of most improvement stores. Generally I do batches of 8 to 12 lures depending on lure size. After I drill and epoxy in my belly wts, I wood fill over the belly wts and sand down. I use a gallon of uncut Spar Eurethane to start the process. Dip plugs and bang lid down to hold em under and prevent too much air hitting the eurethane. Let them sit for a few mins, remove from can and wipe off excess eurethane from lures and hang to drip dry for approx 24 hrs in a warm dry area. ( I like to hang them with the nose end facing up so any drips run to the tail end of the lure, making them easy to wipe or sand off). Be careful to keep soaked plugs away from any kind of flame or sparks.
The following day you can quickly remove plugs from the rebar wire, give them a light hand sanding. place plugs back on rebar wire to be hung during priming portion.
Then, using a 60/40 mix of BINZ cover stain primer cut with mineral spirits, dip each plug for a few seconds and hang to drip dry for 48 hrs. As I dip, I usually use small thru wire cutoffs to help stir out any excess primer from the eye and hook holes.

This combination of sealing technique gives great results, with affordable and easily available products that are pretty safe.

I know many builders prefer to spray prime their plugs and even skip the eurethane process because it can be time and cost prohibitive but I feel like dipping plugs really seals the inside of wood lures and helps to minimize water penetration and logging.

After the primer dries, I sand em lightly on the lathe using 150 to 200 grit sandpaper or emery cloth and hand sand any plugs afterwards that need to get smoothed down a bit ( usually around the eyes or hook holes).

This is just my method and there are certainly plenty of different substitutes and variations that can be used.
