OK, please let me know if you see anything incompatible.
I plan to use the Zinsser 2# sanding sealer over teh entire guitar, then Z-poxy the back side and neck to pore fill, then use about 8-10 coats of Tru-oil as my finish on the entire guitar.
I've never used Z-poxy before and have always just used the Tru-oil to fill pores in the past. I have rifle stock over 20 years old that were done with Tru-oil and no problems yet.
Is there an edvatntage using the Z for filling over just additional coats of T-oil?

I lay down the zpoxy over bare sanded wood. Sand and repeat until the surface is pore free. I shellac over that. The key is that zpoxy does not adhere as well to shellac. However, after prepping the ZP'd surface, shellac adheres quite well.

I can't comment on True Oil.

I'm not sure that there are any "advantages" as such. I have used Tru-oil on my guitars but not over Z-poxy. I like the look of the Z-poxy - sometimes I'm tempted to leave it as a finish in it's own right on the back/sides. It has a nice look/feel and I suspect is pretty tough. Up to now I've lacquered over it.

People fp over it so I would think that Tru-oil will go on fine - but it would be worth trying out on some scraps first to check the look, adhesion and curing of the Tru-oil.

I don't think you will need and sanding sealer though - Z-poxy on the prepared wood I suspect would be best. Others have reported problems of Z-poxy adhering to shellac.

Z-poxy I suspect is easier to apply than the Tru-oil rubbed/sanded into the pores. I suspect it will come down to the looks in the end.

I'm assuming NO Z-poxy on teh soundboard though--correct? Just sealer and Tru-oil

I've used Tru-Oil over shellac with no problems. In fact for the top I'd probably just seal with shellac and then apply Tru-Oil.

I've used Tru Oil over Zpoxy on 5 mahogany necks with good results. ~8 coats total lightly buffed with 0000 steel wool between the last 2-3 coats. I haven't tried using it on any dark toned wood. I wish my lacquer finishes were as easy and consistent.

You are correct, no ZPoxy on the Top, only use the Shellac to seal. TruOil will go over both really well with no problems.

My first three have been tru oil over shellac sealer. I like it.   I also put tru oil on my first fret board, but took it back off as it gave it a plastic look (ebony FB). On my next two I used the LMI FB oil and I really like it as a finish on the FB.

I just tried TruOil on an African mahogany neck. I filled the pores with the System3 epoxy, sanded back to the wood surface after each coat. The TruOil went on with no problems. Looks real nice, too. I plan to finish it up with wax and 0000 steel wool, but I set the neck aside for a couple of weeks to make sure the TruOil had dried good and hard.

Terry, if the neck wood has pores that is the way that I do it, sand back down leaving the ZPoxy in the pores. Then I put a coat of the Sanding sealer. I use the Sanding sealer (same maker) only if I am finishing Maple or Cherry, not pourous and Zinser Seal Coat (shellac) 2 coats if I do the top with TruOil. On the Back & Sides, I sand back but then also put a light diluted cover coat back on to pop the grain and seal then TruOil over that. I have found that TruOil and recently Danish Oil finishes are both easy and work on and over just about everything. Especially the TruOil, it gives a really nice shine that is really smooth. I TruOil all my necks no matter what finish I am using on the body and headplate. Like the feel

Terry,

I've had good results doing the following. I apply the first coat of Zpoxy with my finger and lightly sand when dry. Second coat also applied with my finger but immediately wiped down with a dry clean cloth. Follow up with a light sanding mainly to look for imperfections and repeat if necessary. So, yes, I leave a thin film on mine. Then on to the Tru Oil.

BobK

I haven't used any filler on my mahogany necks. I sand through 800, apply the first two coats of tru-oil with 0000 steel wool, then apply the rest, using the steel wool between coats, veerrrry lightly.
