Here are my top 5 choices for gloss white. In no particular order but Krylon is defintiely 1st. Rattlecans need to be decanted for airbrushing but DO NOT THIN because it will ruin the gloss.
(1) Krylon fusion (rattlecan) - this stuff is awesome comes in gloss and satin
(2) Scalecoat II (rattlecan) - very good paint, nice and thick
(3) Tamiya enamel (rattlecan)
(4) Dupli-color automotive paint (rattlecan)
(5) Floquil reefer white need to add glaze (#110005) because reefer white is not a gloss paint as is.
