SS stays wet for a while so when you get the metalics all standing up nice and even and popping they slowly sink back into the wet paint and lay down.if you get a little too much paint on it will run or sag and the metalics will slide ....
BC/CC on the other hand drys very fast so once you get the metalics standing up and even they get locked into place ,same with pearls.
concider clear a SS solid color paint W/O the color,
since thats what it is,you can do anything to SS paint that you can do to clear.
if you get a run in either it can be sanded out easily....SS metalics can not be sanded, any runs are there for life ,you can sand it flat but you'll also disturb the metalics making a very noticable spot
SS paint and BC/CC are sprayed using completly different methods....SS being the easiest,You just lay it down like you want it to look. Clears are sprayed the same way (they are the same)
base coats are a lot tougher if you lay it on to heavy(like a SS) it'll) skin over (looking dry ) but soft underneath causing problems when the clear is put on because it traps the solvents ,leaving them nowhere to go.
I would highly advise someone doing their first paint job to use a SS solid color. you'll have a more harmonious outcome. if you get runs , dont worry about it ,they'll sand right out and you'll gain even more valuable experiance.
(all good) So start at the begining when painting your first car (solid color SS) ,it takes practice to get it down ,just getting your trigger finger to operate right takes time,very few people are true naturals when it comes to painting and the really good ones had someone standing over them showing them how............save the pretty pearls and metalics for later...Using them could be a very expensive first lesson.....once you can spray a SS paint nice and slick you'll already know how to spray clear the same ,so your already half way there to learning how to spray BC/CC. The most important part of painting is being patient...
