When color sanding a panel use different directions for different paper grits..
For example: Sand vertical with 1000, then when you sand with 1500 or 2000 sand horizontally... This will aid you in "seeing" if you lower grit scratches are being removed...
Also after using 2000 and you think everything is good to go, using the 4000 pad on a DA as our Jclark does really shows up any scratches that you may have missed!!! It ( 4000 grit pad) will give a low gloss luster and remove the 2000 marks, but if there is anything else still left behind it will show them up like a highlight...
Finally let the car,truck/panel... whatever it is set in the sun after you sand it for at least a few hours.. then pull it back in and buff it after it has cooled to room temp... Our own Expert Resident Barry Kives recommends this and I have tried it and it works great... It really does improve buffing and the final product
If you have the time let it set for a day and buff the next day
If you are doing a hot rod ,show car or dark color this is a great help!!
Ahhh its good to be back!!!
