Question Tung oil to Poly?

Sign in to disble this ad
Can a neck with a tung oil finish be changed to a poly or satin poly finish? I'd like to get better protection from the humidity/lack of humidity changes. I don't feel tung oil really seals and protects as much.

Yes, use Minwax wipe on poly. Use gloss as it's a bit more durable. Clean the neck with 0000 steel wool and some paint thinner first. Keep all steel wool away from the pickups on your bass. In fact, put masking tape over your pickups. If you can remove the neck, you don't have to worry about this.

Once the neck is nicely cleaned off, apply the wipe on poly with a piece of paper towel. Not too thick. Let it dry. Very light steel wool again, then another coat. Same routine again if you want a 3rd coat. When you're satisfied it's thick enough, give it a couple days to dry, then lightly dull the finish with steel wool to prevent your hand from sticking.

If you use poly straight from a can, it's pretty thick and you're likely to get big ugly sags. Spray on will work too but you need a lot of masking and an area with plenty of ventilation.

Thanks for the reply. It seems to be a good method. But let's say I did want a satin poly finish done by a pro. How much would something like that cost (ballpark) if I had a pro do it? And would it be worth the trouble? I just think I have to tweak more often than I should. I don't mind seasonal tweaks....that's is normal. But if it rains......or gets a bit damp out.....I need to tweak the rod to get it back to where I set the relief. Then if it's dry.......well...the same thing. This happens all year....not only when seasons change. I'm in for a suprise when I take it out of the gigbag at gigs.....it's a pain most of the time. Then again....I might be a lil too sensitive to the changes.......but I do notice it.

I don't know for sure how much a pro would charge. It's a pretty easy job but does involve a bit of time which is what you'd mostly be paying for. Around here the smallest bottle of wipe on poly costs about $10. I'd charge for a full bottle because, even though you don't use much of it, the stuff hardens fairly quickly once opened. So, I'd probably charge $75 for the job. Each application takes only about 10 minutes and the initial prep work, like removing the neck, steel wooling the old finish and cleaning up, takes about 30 minutes. Then putting the neck back on and setting up the action if needed. So $75 is a bargain I think. Some guys might charge $100.

I don't know exactly what tung oil is used on your bass. Very few of these products are actually tung oil. But, assuming it is, it does allow moisture to get in faster than a poly finish would. Then there's the moisture that gets in to the fingerboard which usually isn't coated unless it's maple. But, I've never had a neck react quite that quicly on any of my basses, even ones where the finish was worn to bare wood. It's worth a shot though.

So, I couldn't guarantee that this would solve the problem for you but it's easy enough to try and inexpensive, if you do it yourself. Unless you're really clueless when it comes to these types of things, do it yourself. The wipe on poly finishes were designed as the easiest finish that could be applied at home to give a decent appearance. I make my own mixture, because the Minwax stuff is just their regular polyurethane varnish thinned with about an equal amount of solvent, probably mostly paint thinner. Mine works just as well and in the long run is cheaper if I'm doing a big job on a piece of furniture. But if you're just doing one small job like yours, a made up bottle of Minwax is cheaper. I mention Minwax because it's usually the easiest brand to find and usually the best price.

Hey, thanks for all that info. The tung-oil on the neck now is a "polymerized" type. Without going too bananas on this.....maybe if I just added more coats of tung oil to the existing finish and build it up more it would help. Then I can always do the wipe on poly if this dosen't help matters. Also...are we talking multiple coats of poly? If so, how long between coats of the poly before adding another coat and how long does this all take to cure so it can be played?

Most of these so called tung oils contain very little tung oil, but are merely a varnish with drying oils and maybe some tung oil added. So, yes, you could use any of these danish oil type finishes and they would bond, as long as you clean and steel wool it first. However, they don't build up to a thick coating and won't stand up to much abuse. They are applied the same way as the wipe on poly I mentioned. The wipe on poly will build a bit faster and offer better protection and is the same amount of work. It's really easy. If you want to go for it, you can send me a pm and I can walk you through it..

The wipe on poly takes about 5-6 hours to dry enough to recoat, so you get 2 coats a day. Give it 2 days before playing and you're fine.
