I started to cheat. I'm now paying a professional and I find varnish work is much easier now. He has achieved a thick glass like finish with a "three" part Urethane based product with high solids by Awlgrip called Awlbrite Plus System J3005.
I've had the stuff on for over 3 years now and it only requires two fast coats once a year to keep it looking sharp. I usually apply it at the end of the season when I apply the Semco to the deck.
The Awlbrite product line is based on a three component system, and so requires mixing the base with the converter and activator.

It says so right on the can...so I figured it was time to let a professional do my bright work.
