What iv,e found with spray cans is that the layers you put on are very thin With 2 pac paint 3 coats is more than enough,but with cans i find 6-7 coats is tough enuough.Also the item your painting must be taken into account.Paint a bracket that sits near the battery will only require 2-3 coats as it won,t see much action.The gearbox however will sit near the road and will get stones flicked at it.Laquer wise i use this.
The can in the middle.
