I'm about to embark on my first transparent finish. It's an alder body that is I believe raw. I want to put a dark transparent red stain from stew mac, the vintage cherry color tone, but I don't know if I should put a sander/sealer coat under it or if that will not allow the stain to penetrate. I've filled wood with straight nitro lacquer before, but not with a transparent finish. The stew mac site seems to skip over this question in it's tutorials. Any help is appreciated. Thank you.
