Urethane is not a good choice for outdoor use and Helmsman is not the best brand. I’ve had a lot better luck w/ Mcloskey’s Man O War varnish for outdoor applications.

I have spayed lots of helmsman with a hvlp no problems but if your only doing one or 2 signs at a time, the set up and clean up is not worth it, properly cleaning you’re hvlp is time consuming and you need lots of thinner or kerosene. much faster to brush. What you need is a bunch of cheap throw away foam brushes or even chip brushes 50 cents apiece nice finish on those small signs throw em out when you’re done, trust me been doing it a long time.

If you’re selling those to customers, consider using something else.

You might look into waterbased finishes developed for exterior use. One is Target Coatings EM9300. They spray well, almost no smell, and dry (not cure) more quickly than solvent based varnishes. Another option is exterior house paint with no pigment. I think it’s the higher “base” numbers that will dry clear.

Using water based, spray guns are easy to clean – warm/hot water and maybe some DNA and things are clean.

Epifanes varnish (Amazon or

The longest lasting non-paint finish I have found for outdoors (even is doing better than some west systems epoxy).
