Tru Oil finish?

[Chistopher]

I'm looking at applying a tru oil finish on my primavera tele body. What is the strategy here?

Light coats with wet fine grit sanding in between?

 

[Chris Pile]

I usually apply 3 coats using my fingers (no lint), let them cure overnight, lightly sand and apply 3 more coats until level. TruOil can be applied thickly enough to buff out to a shiny finish. (not mine - but a colleague).

The wood I'm using is very closed grain, how big of a concern does grain filling tend to be with tru oil?

 

[Chris Pile]

If you want a smooth finish - fill the grain using your choice of materials and methods. Alder, maple, and the like require no grain fill. Ash, mahogany, etc. would require it for a smooth finish.

Hmm... any attempts with a wiping varnish? I forgot I have some on hand and may try it on some scrap wood

TruOil or any petro based finish is not the best thing to apply by hand, health wise fwiw

be careful with any rags etc used with it, they can catch fire quite easily, Soak them in soapy water when you are done and get them out of the house.

I have used wiping polys but never a varnish with very good results. Take your time and practice on something to see what you like best.

Essentially, TruOil is a wiping varnish.

And the material safety data sheet on TruOil mentions NO health hazards.

Wow, that Tele looks great!

I've had good luck with tru oil applying two thin coats, waiting a day, lightly sanding with fine grit (800 I think?) and then repeating several times. I didn't bother with wet sanding and all was good. It comes out looking pretty nice and glossy. I always grain fill before finishing if I want a smooth finish depending on the number of coats you do and the tightness of the wood grain it may or may not matter, but why risk it?

You can add about 30% poly to TruOil to get a more durable finish. Apply the same as pure TruOil.

I usually wipe on 3-6 coats then wet sand with 600-800 grit using the TruOil instead of water. This helps to fill pores. Then continue as many coats as you desire to get the finish you want.

I thought Truoil was petro based, it is not, my bad. It is linseed oil based. Not a true varnish then though
