    I'm not holding my breath that there is (...simple, easy way). Everything I've read sounds pretty involved. Not something that I have to do, but I was just kicking around the idea of having a Alder body being a little darker than the standard clear coat color/shade. Nothing sounds like it will easily mix into Tru Oil. Any thoughts.

    Thanks

    I've not actually done it, but Transtint advertises as being able to be added directly to a variety of finish media including catalyzed finishes. I know it is flexible, but now you got me wondering if it will work being added in directly. I'll try this out this weekend on a little sample and post back. Unless someone has already done it and can post up their results?

    While I haven't used Transtint with Tru-Oil, I have successfully used it with other oil/varnish blends

    I haven't specifically tried tinting Tru-Oil (because I don't really use it any more), but from my experience tinting other similar types of finishes, the two products which will probably work best are TransTint and Mixol. Both are considered to be "universal" and are able to be mixed into any type of finish. TransTint is better for transparent tints. Mixol is better for solid opaque colors, but you can mix in smaller amounts for partially transparent colors.

    With some finishes, you need to first mix the TransTint/Mixol into a little bit of denatured alcohol first, then mix that into the finish. With any of them, you need to do a lot of stirring, like several real honest minutes, to get it thoroughly mixed.

    If you are trying to darken alder a small amount, use orange, maybe with a little bit of red or brown.

    Important: The more tint you put in, the more difficult it's going to be to get the color even all over, without overlaps and blotches. Go lightly. Put in just a small amount of tint and build up the shade in multiple coats. Don't try to get the color in one coat.

    Hey Bruce, you are wonderful sir.

    Thank You
     
  7. Tru oil is somewhat amber already, I suppose if you were very diligent you could build up a half billion coats to make it darker. Or just take Bruce's advise since he knows his stuff.

    Bruce provided great advice :)

    I would add to pay close attention to your end grain if using TransTint dye. It can get very splotchy and un-even. If not really addressed you might end up wanting to make a dark burst to hide it. Proper sealing is supposed to address this possibility but it isn’t iron clad (so far with my experience)..

  9. I’ve never tried it but my thought on getting the color even with a tinted Truoil would be to apply a few coats of standard Truoil to seal the wood then apply the tinted oil and then, if you want, more standard Truoil over that to lock the color in.

    Why does that sound like a good idea?

    I’ve used Truoil a few times and it has a natural light tint to it. This would give you an idea if you like it as is, and get the benefit of sealing. If not then you can proceed to tinting the next round of Truoil to get it a bit darker. I would try practicing on maybe an inside control cavity if possible.
     
  14. With any stain the endgrain will soak up more stain and appear darker. Also, depending on the wood, there can be areas that soak up more stain making the surface appear “blotchy.” By sealing the wood with a coat or two of untinted oil it will help the stain go on more evenly. (Theoretically) The down side is that on ash or figured maple, for example, the grain or figure won’t soak up more of the stain so you won’t get that “pop” or PRS type effect.

    Testing on offcuts from your body would be ideal. Ymmv, etc.

    Huh, I completely forgot about this thread. I did in fact test Tru oil with both transtint and also with mixol colors. Both of them worked fine. I tried adding the Mixol to some denatured alcohol before adding it to the tru oil., but a very small amount goes a long way obviously, because even just a few drops turned it pitch black. :)

    Hey, @briandaviamurph, I know this is an old post, but would you mind sharing with us your formulation—the color or colors you used, and their proportion? Your results are spot-on to what I’d love to see on my bass. Thanks.

    I used artist paint as pictured and mixed a very small amount til it looked right, You need to use a paint with linseed oil base [called oil paint]. I have pictured the paint and the finished results and I am very happy with the outcome
