Has anyone here used Minwax Polycrylic on a sparkle guitar?

Interesting...using the shaker for the flake makes sense.

I think you'll like the EM7000, JA'. I've used the EM6000 for years as well as its predecessors and started in with the EM7000 on my very first guitar build last year.

 

One of the big complaints over time with waterborne finishes is that they historically have had a "colder" look to them. Target's EM6000 was formulated to emulate solvent based lacquers, both with "burn in" as well as having a warm color. That's likely the reference to a slight amber. They are clear, but not quite as "dead looking" as many other waterborne products including the one in the title of this thread.

 

I do not sand between coats for these finishes...other than lightly knocking off any "nubbies" after the initial coat or two if it went on bare wood due to grain raise. Now if one screws up a bit and gets too much orange peel...leveling prior to spraying final coats can make for less work of "finishing the finish"...the same as for any other kind of product one might spray regardless of type.

 

Obviously, nobody here is talking about a finish that has any musical advantages, or even positives, to it, so once that concept is down the toilet, I think you're looking at an amount of build that will allow your flakes to occupy some 3D space (= shimmer reflections) instead of just sticking flat. I would never put poly on a guitar, period, but I do use it for custom stompboxes and have found Minwax Polycrylic to be thinner than many high-build polys. I like it for that reason, but think it probably gives less depth than other polys might.
