i use it a lot on used cars or beat up cars that have some of the crash damage done. it basicly sprays the same as dbc but shopline doesn't have the basecoat additive to speed up cure time. i use dbc additive without problems. the additive is dx84 or 87 i can't remember the correct number.
coverage is hit and miss. the paint store can convert over a single stage formula to a base clear formula by adding 100% basecoat clear tint and binder tint to the single stage mix which already has single stage clear tint. because of this the base won't have decent coverage.
ask the selling dealer if the formula is a basecoat formula or a converted formula before you buy it.
