[QUOTE="Shadowrider, post: 1712572, member: 3099"] It totally depends on the specific type of paint they used. Not the brand, the type. If they used an old style acrylic enamel or acrylic lacquer then sanding and clearing is perfectly fine. But I've been around a lot of people that paint custom bikes, cars and trucks and from reading all the forums that I used to frequent constantly, I can say that I haven't heard of or know of anybody that uses those paints anymore. They use basecoat/clearcoat system because they are fast, easy to work with, very durable and they look great. I honestly don't know what it will look like because I've never not cleared basecoat in the same day. They (PPG, DuPont, House of Color, Nason, friggin everybody) all say it's to be clearcoated within a very specific time frame and that's a matter of hours usually whether it be automotive or aircraft paints (I've done those too). I suspect you will have the clear not adhering to the basecoat or the base will color fade badly. Some sort of serious issue like this because a chemical reaction between the base and clear takes place. They are chemically designed to go together and it has to be when the base is fresh. House of Color used to (and I'm sure still does) make what they called an "intercoat clear" specifically for complex graphics that take alot of time. You would shoot the base and maybe a layer or two of airbrush graphics. Then hit it with this intercoat clear. Then you could do more airbrushing over the next day or two without worry as long as you used the intercoat clear over the basecoat graphics as you apply them. Then you put the final clear on after the last basecoat graphic is sprayed. The moral to this story is with basecoat/clearcoat systems you spray the clear as soon as the the base has just dryed. Always. As I said before, find out what paint they used. If they are old school and are doing an old school hand rubbed lacquer type paint job, you are fine.
