I'm making a dining room table out of doug fir and I'm trying to figure out the best way to protect the wood, if anything. I stained the whole thing first and then painted over it. Normally the paint would be all I would need, however I was going for that distressed, old worn look so I used my sander to basically take away a lot of the paint. So there's some paint covered areas and some areas of just the stained wood showing. Not sure if I should use anything to protect/seal it. Normally I would use poly, should I just do that? Some type of oil or wax? Or something completely different?
