Episode Details

Engraving plus an oil-based paint marker gives you two independent failure modes — but some environments demand a third layer. This episode breaks down four families of sacrificial coatings: wax-based films, silicone conformal coatings, spar varnish versus spar urethane, and two-part epoxies. For each, we cover application method, cost, and which surfaces it suits best. Then we get into the trade-offs that actually bite: adhesive failure that peels your paint off with the coating, solvent-borne formulations that dissolve the very mark they're meant to protect, and why re-coating is semi-skilled labor while re-marking is not.
