What single stage paint can be used under Imron clear ? Also isnt velvaseal required before topcoat ?

Merry Christmas !!!!

Dupont, Centari is a great , durable, and glossy paint---but why Imron ??--Imron is only as good as its base and will not shine as well as Centari, but is a extremely durable paint if applied correctly---I have used both with excellent results---I also think that a single stage paint is as good or better than a 2 stage.....

I really don't see the advantage of using a SS and then clearing it. Why not simply use BC/CC and be done with it. Do you already have the clear?
