I decanted the TS13 and airbrushed it on for the first 3 coats to build up a barrier. It worked OK but the finish was not as smooth as I wanted so I took a big gamble and shot on some more from the tin, lightly at first and the last coat was a nice wet coat.
The finish still has a slight pebbly texture but I can sort that out.
I think I will rather stick to my acrylic as a gloss coat in the future.
