   According to the Penetrol web site (http://www.flood.com/Flood/CustomerSupport/FAQ/DIY/Penetrol+FAQ.htm), their product is not intended to be uses as a thinner. It is a conditioner that improves the flow out or smoothing of an oil based paint when applied to a surface.

   If you want to thin an oil based finish, use mineral spirits, paint thinner, naphtha or turpentine.

   The most important thing to be aware of when spraying is to use a nozzle intended for the viscosity of the finish. It's best to minimize thinning or you can end up with bubbles, runs and sags.

   Thanks to you all. Saved me from my first big blunder in painting this project, I wonder what the next might be.

   Again thanks I'm sure I would have done it wrong.

   I think the real issue isn't why you should be using thinner and not Floetrol to thin oil based paint for spraying, but whether that is a suitable product to spray.  It certainly can be done, but oil based paint dries so slowly that the overspray is likely to make a major mess on all surroundings and also potentially bounce back onto the surface.  To do this right requires real spray booth with proper, and safe, fan and filter evacuation of the overspray. 

   There are waterborne finishes specifically designed for spraying that can be tinted to almost any color.
