If it’s not dried up it’s fine. Use it. I love that stuff for an oil finish.

 

If it isn't dried out it should be ok,

What's it going to hurt putting a layer on?

 

If you store this up side down it will last a long time. Tru oil is good stuff.

 

Tru Oil is a good product when used correctly, and it can result in several types of finish, depending on method. The oil develops a crust on top when it's opened and stored. Over time, the drying agents in the bottle will be used up in this process, and drying time will be prolonged, the longer the product is kept and used. Eventually, the drying time will be very long, if it even dries at all.

It's inexpensive. As long as it dries fully and in less than a couple hours, use it. If not, buy another bottle. I keep a large bottle on hand for my stock finishing customers who specify Tru Oil finish

TORC12 hit the nail on the head on storage. Be careful with this stuff on the checkering as I have heard it can turn it to mush.

 

If it is old and too viscous, You can thin it out with some mineral spirts which also help to cure and harden it when applied.

 

I have used it quite a lot over the last 20 years. I find that the finish stay's sticky if you keep it to long. I replace it a couple times a year and I find that it works better that way. The older it is the longer it takes to harden and dry to a smooth finish.

it comes in aerosol cans. does not dry out, easier to use, keeps forever. doug

 

I have used dozens of different finishes and oils. My experience has shown ME
that Tru Oil is the all around BEST gun stock finish at any price. I would
throw away the OLD BOTTLE and spend the 10 bucks for a fresh one. I cut mine
With Japan Dryer.....and NO....when I finish checkering I use an old toothbrush
To rub a coat in to seal the checkered patterns.

I use the toothbrush also for the checkering. It works great. Brownell sells a nifty brush that is stiffer than a toothbrush that also works very well.

 

Yeah I think I am gonna toss this one and get a fresh bottle - it's cheap enough that I dont mind - especially to keep a beautiful claro walnut stock nice and shiny

 

Also, do not remove the foil sealing the bottle; just poke a very small hole in the foil to dispense the product.
Store upside down as suggested above.

 

One of the GREAT ADVANTAGES to Tru Oil is that it is READILY AVAILABLE
as well as INEXPENSIVE.......STORE IT UPSIDE DOWN.....OK!!!......BUT ....to
be able to MIX IT.....one WILL NEED to remove the FOIL!!!

 

+go to your local dollar store and buy some marbles,when finish using that product put some marbles in to fill bottle to the top ,that gets rid of the air last much ,much longer

 

YES !!!....that works....I have done it with some EXPENSIVE London best oil that
I tried.....but found that it was NO BETTER than Tru Oil and WAY MORE EXPENISVE !!!

 

I store it upside down and try to shake it every day if I remember, also I use lighter fluid to thin it, Japan thinner works too.

 

Mine was a little - thick would be the right word. It was about a half bottle that had been in my garage for about a year. I tried letting it sit inside and it didn't change. I grabbed another bottle and I will store this one inside upside down.

 

I don't use Tru oil on the checkering, for that linseed oil is best.
