Hi Siegmund52 , here is my 2¢ worth:
- First, as you may know: 99% of the job is prep work. Paint is the remaining 1%... One think to look into is the new, very high fill tinted primers. They are FANTASTIC to work with. You will end up sanding off 90% of it, but whats left makes a LOT of difference. A big +.
- base/clear systems have become the norm, nowadays. Every company has it's own, proven system and if you stick with the major brands and do NOT intermix between own and the other, you will have great results. They are very resistant.
- Having said that (and what follows is only based on my experience in restoring vintage motorbikes) the base/clear systems tend to give a more 'plastic', high gloss shine. What do I mean?
Try this at home: grab a tasty sweet red apple and buff it to a high gloss with a cotton cloth (dont bite yet). Looks nice and bright red, right? Now take a piece of 'cling' wrap and wrap the apple real tight with it. It is shinier, slicker and reflects more light, but kinda 'turns off' the color, doesnt it?
That's why I use the 'older' acrylic enamels or acrylic urethanes. I dont want to sound obsessive/compulsive, this is ONLY in a case where you'd want to preserve a more 'original' finish. Touch ups are easier, too.
Just an observation,
