While in the process of modifying the pups on my Cort Action 4stringer I have been pondering a change in the finish on it. Maybe sanding of the walnut finish and tung oiling the Agathis(though its a plain looking wood). I know someone here has experience with refinishing or finishing for that matter a bass, so I want to hear your stories, suggestions, and comments on finishing at home. Glenn
My tip, do it... just take your time, make sure you have all the necessary supplies, read up on techniques and application and most importantly go through the entire process on a scrap piece of wood. I recomend using nitro-cellulose, and www.Stewmac.com and www.reranch.com both offer it in spray cans. Go to www.reranch.com and read everything there, than you might find that you could do a nice color, tint or dye over the wood. I recomend a solid color since like you said, Agathis lacks a defined grain pattern. I have a warmoth thread that documents my finishing or a body, and I just recently completed the finishing process on the body and neck. http://www.talkbass.com/forum/showthread.php?s=&threadid=90113
You can use many things, the most common being poly and nitro cellulose. Both come in gloss and satin, and either creates a hard finish. Nitro is a decent amount thinner though, as coats melt together, while poly simply stacks up each coat. Either is a great finish for necks, but don't don't forget to coat the fretboard if it is maple.
