All 4 coats of S3 Topcoat are on, so here are a few thoughts I had.
I personally preferred the roll and tip vs. the spray. The 1st coat was sprayed, it took about an hour to apply, and about half an hour to clean up. The roll and tip took about 45 minutes to do, and about 5 minutes to clean. The coating was more even and thicker when rolled. The paint is now dry and void of any brush marks. Last 2 coats had the crosslinker.
I thinned about 20%, except for the bow area. For the last 3 coats, the only runs I had were in the tunnel.
The S3 Topcoat is EASY to use...when its 60 degrees and high humidity. I don't even want to think about doing this in 90+ degrees
Fumes were very minor. I did most of the work with the garage door closed because the wind was blowing pretty hard and I didn't want any leaves or dust settling on it.
I'm not saying its a perfect paint job, but its better than I expected. I guess its a waiting game to see how hard and durable the coating is. I'll try to roll it out in the sun tomorrow and get some good pictures.
