How Long Should I Wait Before Sanding 2K Primer?

I'm getting ready to shoot 2K primer on my 1970 Mach 1 project. I've read it's a good idea to let the 2K primer sit for a while, to allow for shrinking, before sanding. Is this true? If so, how long should I wait before sanding?

I'm using SPI 2K primer.

Thanks.

I read where a day in the sun is like the equivalent to a week in the shop. Check out the SPI forum, its got a ton of info.
