well i used TB epoxy because it is supposed to be the most durable finish out there...i used many others before it and they did not hold up...once i spent all week applying tru oil then smoothing it with steel wool, then applying, etc...only to hit the door onthe way out of the shop and scuff a tip..
I just started using this finish so I havent been able to give it a full durability test but...it does go on farily easy and sands nicely before it it fully cured.
I will apply it by mixing a batch and applying a sealer coat, then sand, then another, sand...now the pores should be fully sealed...write on the specs (i.e. 54@ 28) then spray on 2-3 thin coats.
