I've painted quite a few old cars over the years but I have some how managed to avoid painting a metallic. I'd like opinions on the best basecoat for a fairly dark graphite silver for a newbie to spray to avoid mottling and striping. I'm spraying air dry in a garage so was thinking Lechler BSB, max meyer, ??? colour match isn't Cristal as the whole car is being painted in an old colour. Ideally, I don't want to pay glasurit money but if it means not doing it twice because it's easier to use I would think about a more expensive brand. Clear wise I would prefer something compatible that will sand and polish well and hold up for years on a garaged care. Any help appreciated, Thanks.
