AH the JOYS of learning to spot repair

I have been refinishing for 30 years and with the new BC/CC's it has made spot repairing much easier, untill you get to the pearl coats and tri stages .

I highly dont reccomend blending out the clear Only if necessary , if you dont have a break off point. But if you have to blend a clear edge I use a wounderful product I found to work excellent called UPOL 20:43 fade out spray ( comes in an aerosol can & developed overseas) its incredable stuff !!!!
Melts that clear edge so well you cant even see it .
But use it sparingly ( spray from 12' away from clear edge , one light coat , let sit for 30-40 seconds then one more light coat ) as to much it will make the clear edge run , then you have another problem

say you are spotting in a door I would sand whole door with 800 grit wet or dry , then spray down DBC 500 blend clear over the whole panel ( trust me I do this over every spot I do as it fills the light sand scratches so metallics and pearls dont get trapped in the sand scratches and show after clearing ) then mix your color like PPG says , then using a little lower air pressure spray first coat in the area that needs color , the next coat a light bump up in air pressure on gun and spray another coat about 2"- 4" past the first coat, then another bump in air pressure and the 3rd coat sprayed about 2"-4" past the 2nd coat , this helps in keeping the over spray down that I think you are seeing. lightly tac the door and spray 2 coats of clear and your done !
any small dirt imperfections just water sand flat with 1000 - 1200 grit and buff.

Hope this is helpful.
