Spray painted the inside of the fiberglass cabin top with UV Smooth Prime using the new TCP Global Brand Professional 2.5mm Hvlp Spray Gun purchased on Amazon for its larger 2.5mm nozzle. This gun worked very well with the thick UV Smooth Prime which was slightly thinned with water using the 5:1 ratio recommended on the can. This is a much better spray gun for thick materials than any of the others I have tried. Sprayed 2 coats with about 1 hour between coats. Sprayed outside as it was a nice day with little wind.
