I've been using General brand finishes lately. Gel Poly is my new fav topcoat. Wipe on - wipe off with a paper towel. Easily re-treated in future. No overspray, masking, etc.
I've developed a pretty trick sequence to apply if you're interested.
For sprayed finishes I only use a hvlp gun. No rattle cans. Same company (General) also makes a very durable water based varnish that sprays well, sets up overnight and is very durable. I'd have to dig for the product name - have some out in the shop.
