Take a look at General Finishes

Not only do they have a clear poly – they also have pigmented poly in black or white and I think you can even get it custom tinted.

It’s not cheap (around $60 per gallon) but I have had excellent results – especially with the black poly. It dries fairly quickly, pretty easy to sand and can be recoated in less than two hours

here is a link where you can look up vendors in your area

also, take a look at their “High Performance”

Regarding your fish-eye problem…. could it be related to cleaning your gun between finishes leaving some residual soap or mineral spirits in your gun? Did you scuff sand the under coat (Varathane I think??) before applying the Ace brand, wipe it off with rag that could have been contaminated?
I have limited experience with WB poly, know only enough to ask questions.

I use a lot of General Finishes – mainly High Performance although also have used their outdoor finish GF 450 (seems pretty good on small fold up table we use when camping). I use a foam brush so no experience with spraying. Have been applying finish in my living room so like the low smell!

I cleaned the gun briefly with just warm water, no soap. I like to make a habit of doing this any time I need to refill the gun mid-project to keep the tip from getting clogged and such.

On the thick overspray “pools” on my workbench, I did notice an “oil slick” look on top of the wet finish after spraying the Ace stuff.

Also, the Ace was going down over raw wood, no previous coat of finish on that side of the piece yet.

Anyway, I’m happy so far with the Old Masters, but I love GF Arm-R-Seal wiping varnish so maybe I’ll give their WB poly products a try. Thanks!
