runs in clear

[pleej]

been painting for a couple of weeks now on old body parts.
priming good
spraying colour ok

when it comes to spraying the clear, i cant help but get runs.
set the comp to 60psi
i mix 2 to 1 with 10% thinners but got told buy a sprayer to add more thinners so tryed that .
i give it one dry coat then one wet coat and still get run's
can any one help

i also watched so youtube clips and they seam to apply alot more clear in one place than i do

How far away are you holding the spray gun? Adding more thinners will make the problem worse not better. You don't apply anything in one place, the idea is to keep the gun moving parallel to the surface and overlap the fan by about 50% so you don't get a dry line.

As above I also think you may be holding the gun to close to the panel. And also make sure you have the spray area warmed up so that the paint will flash off much quicker

i dont mean i was holding it in one place ,on the vids it looks like they lay more down in any one place than me.

so i could be using too much thinners and heat the part im spraying up .

thanks for the info

i hold the gun about 8 to 12 " away

so is the mix 2 to 1 + 10% thinners ?

2-1 +10% thinner is fine, you shouldn't need anymore thinner. Not sure what lacquer your using but some of the compliant one's don't need a thinner.
What size setup do you have ???
Have you got the shop up to temp ???

im using omi-cron products

i use the small spray guns and a small comp but i do have a full size gun that ive never used.

i think the garage was probly cold too, i had a heater on but its only small

I reckon your problem is heat, you not only need the work area warm but the panels too, it was pretty cold the other day and i struggled to get my shop to 75F

Those small guns have a 0.8 setup usually so wouldn't think it is that, what size area are you painting as those small guns have a pretty narrow fan.

Which clear are you using?

 

[Chipper]

Are you letting the mist coat have some time to flash, before going on with a wet coat?

 

[pleej]

omi-cron clear

yeah i let it dry, from doing some searching it looks like it was too cold and i had it too thin.
