Balsa sealant?

10 posts in this topic

I often use slightly thinned Devcon Two Ton epoxy but there are choices as long as the coating is durable, hard, and waterproof.

I've used polyurethane, minwax wood hardener and spar urethane on cedar wood.  They all do a decent job.  For a real smooth painting surface though, a layer of epoxy (or superglue) seems to work best.   But, I've never used balsa.

I like runny super glue for balsa, because in penetrates into the wood on the first coat, so a two coat deal makes the softer balsa's surface much harder.

Propionate works well but it has some downsides.  First, it’s hard to find prop pellets for sale.  A couple of TUers sold it years ago but not any more.  Prop needs to be dissolved in acetone, onto a fairly thin solution.  Then the lure needs to be dipped anywhere from 5 to 8 times to build a sufficient coating thickness, with pauses between dips to allow the acetone to flash off.  Afterwards, you should let the coating sit overnight to fully harden.  So it’s a rather labor intensive coating compared to most other options. But it does make a nice undercoating.  If you are building a batch of 5-6 lures, you can dip lures almost continuously.
