[AT] Tractor painting--Charlie and Louis

[Louis Spiegelberg]

Usually you need to follow the flash times recommended by the paint
manufacturer.  Some paints and primers you have a window of a few hours to
paint.  If you miss that window, you have to wait a period of time,
recommended by the manufacturer.  As far as sanding goes, again you have to
ask your supplier about that.  Different paints require different
techniques.  

If you do have to sand, you might want to use a scuff pad instead of paper.
It is faster, less clogging.  Make sure you get it all wiped down good after
sanding/scuffing.

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.
