change of color...

^^ And have it look like a bass boat and have the texture of sandpaper?? Ick.

PPG makes a couple different levels of quality. OMNI is the low end, DBC is their middle of the road color/clear, and their Global refinish system is top shelf stuff. The shop I work at sprays Speis/Hecker color and clearcoat and it's very high quality, but also very high priced. Valspar makes a decent quality paint that is also pretty cheap, but I'm not sure if they have a basecoat/clearcoat line.

As far as better/worse colors in black, there really aren't any that are "better" than another. The only difference would be the pearl/metallic flake in the basecoat. I would suggest that you just look through some color match books and use whatever the school shop has on the mixing bank. Chances are, it's decent quality.

I said big pearls, not big metal flake. You need a fine metal flake if you go that route. Also, it won't have a rough finish if you do the prep right. Your final layers of clear should not have effects in them.

You want all the additives and effects to be in the basecoat. Or if you want to be fancy, you could lay down a basecoat, then a transparent mid coat ontop of that, and depending how many coats you put on, will determine how much that color stands out. You don't want to put any pearl/metal flake in the clearcoat at all, whatsoever, no matter how many coats you put on top of it.

Straight from the House of Kolor website:

"KAMELEON® PEARLS (KPF)
The color changing effect of Kameleon® Pearls are just as dramatic as the Kameleon™ Base coats Available in four color changing pigments, they are in dry form and may be added to SG-100 Intercoat Clear or any of our acrylic lacquer or urethane clears. The pearls can make a vehicle appear to be different colors to people looking at it from different angles. Use these pearls to add an exciting flare to your artwork.

KAMELEON® OPALS (KOP SERIES)
Kameleon Opals represent some of the latest advancements in pearlescent technology allowing radical color shift from different viewing angles when sprayed over black and darker colors. These colors can also provide an opalescent effect when sprayed over white and lighter colors. These products are available as easy dispersing powders that can be added to clears, pearl base coats, and Marblizer® to create dazzling effects and exciting new colors."

So, can they still not be added to clears even though HOK says that you can? I also had a white race car with a blue pearl clearcoat over the original paint. It was not rough at all and looked cool in the sunlight. This is very popular down in Florida, they pearl cars all the time to make them stand out.
