Is it OK to thin out Flexcoat lite with a few drops of denatured alcohol?

This is for silk thread penetration.

Or should I just go out and get some rubbing alcohol?

Used it with West System on my boat and it didn't sink.

It did break in two when they dropped it but, not where I batched it.

See you on the water, Doug

DNA will work fine, always thin the epoxy with it for the first coat on silk. Remember though, it will slow down the curing somewhat.

IMHO acetone would be a better choice.

Doug,
Actually, it is NOT all right to use DNA.

You really want to be using either Acetone, or Xylene.

Essentially, Acetone and Xylene is a solvent for epoxy resin.

DNA is NOT a solvent for epoxy resin.

To prove this you can do a little test.

Basically put three brushes into the resin finish. Then, pull out the brushes and dab away some of the resin. Then, let is cure for about 15 - 20 minutes or so. Then, use DNA, Acetone and Xylene to clean each brush. You will find that Acetone and Xylene both clean the partially dried resin very well. But you will find that the DNA does not do a very good job.

You can also do the solvent test.
Mix up a small batch of finish. Then for three separate batches, put in about 1/2 teaspoon of DNA, Acetone, and Xylene into each batch separately.
You will find that the DNA, really does not mix with the resin very well. It just stays separate from the Resin.
But for both the Acetone and the Xylene, you will find that the solvents essentially disappear and become one with the resin.

The other thing that I know happens very much if you do attempt to thin with DNA and that is that the finish becomes very rubbery and very spongy. Not the case with Acetone and Xylene. A good part of the reason that Acetone and Xylene does so well, is that it has a very fast flash point. That is, any residual Acetone or Xylene evaporates, before the Resin cures leaving no solvent behind.

But DNA with its much lower flash point does NOT all evaporate away during the cure, and it becomes trapped in the mix causing the soft and spongy.

Good luck

Acetone is the better solvent as it's more volatile and will leave the mix more quickly. You don't want a solvent trapped in the cured epoxy.

Just put on a thiner coat, which unless you are using a high quality brush is difficult to do especially if you use a spatula as some like to do, or a cheap throw away brush.
