hey guys, im going to be re doing the side of my car for mottle. whats the procedure? im gonna be spraying Onyx HD. can i just scuff and mix one to one with the clear blender and lay 2 orientation coats? thanks
I am not familiar with Onyx but if it were me I would rebase and blend as needed. I can see you having an issue with sanding it and just putting orientation coats on. I would treat it the same as if primer were underneath.

I would tend to agree. Sometimes mottling can be from your 1st coat, and the subsequent coats are unable to correct it. Re-base over it and try again. Can you figure out what you did to cause the mottling, and correct that on this application?

Now there is a leading question lol. mottling can be caused by many many factors
I worked with a pretty good painter a few years ago, as a painter he painted very fast, but he also painted very close to the panel a lot closer than i do that was why his arm used to move about twice the peed of mine lol.
As a result he on occasion used to get mottles.
This was due to the fact the gun was to close to the panel and he was not getting full use of the fan pattern.

That sounds a lot like me!I have to force myself to go a little slower and further back with base, otherwise I too can get mottles.
make sure your useing the correct temp recducer too. i would also agree with the others, a rebaseing is in order, a orientation coat won’t due much, most likely won’t even cover.
you guys ever do a metallic and on the last coat drop the pressure way way down like to 10psi and pull back a little, that seems to kill the problem all together including any type of zebra striping, but the key is I find with metallics is to let them dry real good between coats and def. tack after every coat
