Spraying jambs and other tough to get area's?

[DanMcG]

I hope to spray the jambs on the truck in the next couple days and plan on using my lph400. I think I should crank the fan down for a narrow pattern and also crank the fluid in to accommodate the fan. Would I also reduce the air pressure at the gun. Or am I totally wrong on this?
I hope to get epoxy and color on them in the next two days, after that the outside paint booth will be closed for the winter.

You can reduce fan but don’t reduce air pressure. Maybe a little less fluid.

That said, I just use the same gun settings for everything.

Thanks Don, I guess I'll try it your way then, you haven't steered me wrong yet.

I panel paint everything so I paint jambs same time as the large panel areas. That’s why I don’t adjust gun settings for jambs.

Yes, just turn the fluid,fan down as you test spray on some masking paper till you get a pattern size your comfortable with but as Don said,leave your air psig at normal say 18-20#,fluid at 1 1/4 open,fan about 1/2 open from closed depending on the paint used to start.
What masking paper is good for instead of the Work.
Painter's who spray a lot are comfortable with this and basically change nothing but their "touch" on a full size gun which only comes from Experience.
Set your distance away around 5-6" and spray a full trigger pull for about 1 second and release and adjust to a good cigar pattern with full coverage. Fan determines the size, Fluid the coverage.
Piece of cake.
