I use that combo (50/50, 60/40 Eth/Ace, 70/30 Eth/Ace) in a commercial spray application and in limited use as a wipe on, but not with transtint dyes.
Depending on your mix, you can alter the ‘open’ time of the dye stain to alter the dry time. It really depends on how you are applying the stains though.
For spraying, we use it as an accelerator for drying. The open time will affect the color of the finish, especially in more humid/warmer environments. Generally speaking, the faster it dries, the harder it will be to control how blotchy it will get and the more it will tend to lay up on the surface.
The converse of this is using 100% DNA has a tendency to be too wet, leading to what we call grain pop. It gives a mottled look to the grain and will hide the character in cherry and maple. I’ve seen this when using NGR’s as wipe on, and it’s something I personally don’t care for.
Acetone usually has a little bit of water (<3%) in it but that should not raise the grain much. A light sealer coat of your choice followed by a light scuff with 320 or higher sand-paper will take care of it.
