[AT] Tractor painting--Charlie and Louis

[John Wilkens]

Thanks for the quick response Charlie and Louis!  Since I've never 
seen a coat of paint "not stick" and just peel off :)  I assume then 
that the misting relates more to a method that reduces sags and 
runs.  Sounds good.  I'm using the recommended HVLP air pressure 
(maybe a little higher) but I haven't checked the tip size.  I'll 
make myself try it again.  I am using a catalyzed primer sealer--wet 
sanded smooth.  Last night I applied my first ever coat of color 
urethane and am impressed!  Good cover, no runs and very shiny.  Now 
I need to know if I should wet sand this nice shiny before applying 
the next final coat?   Looks too pretty to mess up with sand 
paper!        Thanks again.   John W.
