hi there ,
I used wattyl sigma dur poly u 400, Used the old coat as primer filled and spot primed where required, Always when spraypainting be sure your first coat (mist) is a dry-ish coat,and that you give it 1/2 hr to tack off,then proceed with a more liberal coat . Remember to look closely after prime coat that ALL filler is coated and that there is no filler colour still showing ,if so re prime that area,or (mist coat) the blemished area's. Dark pigmented paints will cover better than light or off white colours. good luck, atomization is also a critical factor in good spray finishes.
