I am painting my 72 comet and it is my first automotive paint job. It is working out with alot of repainting. I am using a base coat clear coat paint. I have painted most of the car in pieces and have sanded and buffed the paint to get the finish I want. Most of the car looks really good but I got some runs in the clear coat on the back quarter panels. I have sanded and buffed the paint but you can still see the runs when the car hits the sunlight right. My question is: Can I scratch the clear coat and spray a couple of more layers so that I do not burn through trying to remove the runs, or do I have to sand it all the way down and start over?
Check out this tool: http://www.tcpglobal.com/autobodydepot/runnib.aspx Any good paint jobber should have one to sell you. Since you're not cutting down to the base coat you should be able to scuff the existing clear around the area and put another clear coat right on top.
"was developed over years of testing in the paint shop by experienced painters looking for perfection." ...how experienced were they if they need a tool to remove...sags and runs...
Every painter get a sag from time to time...Its how well they can correct it that makes em painters...A nib file is what you need to "file" down the runs. Then you can color sand and buff the areas and you will be good to go.
Thanks for the help..What would be the best way to scuff the area so that it won't show under the new clear coat? I am a complete novice and I don't know what it means to color sand.
Use 400 grit wet sand paper...Backed with a soft wet sanding block. After the sags have been filed down...Wet sand the entire panel you are painting/clearing untill the whole surface has a uniform sanded appearance and no flaws are visible.(dont cut through the clear to the base coat) Then clean/dry and prep the surface and re-clear the panel.
