Re: Getting some wrinkles in old Salem clear sealer
I'd let it dry for a while, then take a sharp cabinet (card) scraper to it and level out the defects.
Build up coats of varnish, sanding between coats with maroon Scotch-Brite pads. Give any runs, sags, curtains, etc. in a coat the sharp cabinet (card) scraper treatment just before putting on the next coat. When the finish gets too ropey/rough, use sandpaper on a hard rubber block to block it out and level it. The only coat that truly matters is the final coat.
To sharpen a card scraper, you'll need 3 things:
- A burnisher. A piece of hardened drill rod will work. So will the chuck end of, say, a 1/4 general-purpose drill bit.
- A mill file. I find a jig like this useful as well,
to keep the file square WRT the scraper blade. You can whip up the same thing pretty easily (a block of wood, slotted to hold the file with a thumbscrew to clamp the file in place.
- A fine oilstone.
