guys i got some paint from nissan it was in a tin n on tin it was a base coat(only 1 nissan gave) but after spraying it on it doesnt look as shiny as its meant 2 b to match car (even with several coats its only like a slight matt looking like finish) am i meant to go to homebase n get some clear glossy varnish(they only do wood clear varnish samething tho isnt it as long as its clear) n go over it to give it that shine? (it did say on tin use varnish but i aint so sure so asking first b4 i stick varnish on it )
