"Finished a very large bookcase in no time"

Hi Roger,

I'm pretty much stoked with the Fuji HVLP system. I just finished a very large bookcase in no time. Finish was satin poly and came out smooth as glass and the coats built up in no time.

I have a question regarding thinning my poly. Some brands are pretty much ready to spray out of the can and others are quite viscous and need thinning. My question is this: Are there any thinners I can add that will decrease the drying time? I thinned the poly I used with mineral spirits. Is there a better thinner to use?

Thanks very much!
Michael
