Pearls can be a bitch to get to lay with out blotchyness and with out good gun skills and the more you lay on the muddier it looks and and takes on a whole different color , it takes just a little bit in mixed clear and 2-4 coats , to achieve the effect .
Its easier if you play with a spray out panel( like a hood or deck lid ) first to mess with till you get what you want , but like I mentioned before it takes quite a bit of money to just play around with ,or if you dont have the material laying around to just play .

But it can be a fun time to learn
