theres 2 types of candy.
2 stage transparents and 3 stage dormants.
2 stage is either a metallic or bright (chrome style, 95 +/- depth) under coat and then a partially transparent top coat to allow the under coat to shine through a bit.
Dormants can be either 2 or 3 stage. 2 stage dormants follow the same as above except the dormant is the bottom color with a clear as the 2nd stage.
3 stage is a base coat (black, chrome silver, etc) then a transparent dormant, then a clear.
NIB legs require prep regardless. NIB black stern legs for example need to be stripped/blasted. New BW legs still have that coating/chroming to them that needs to be sand blasted off.
The only ones that need no prep are the raw legs/rails you can get from one of the vendors here (I won't say who) and even then i blast them to make sure the substrate is even.
Here is a pic of parts that have been stripped and blasted. image.jpg
