hey guys, I painted the rear valance on my 72 with BC/CC and was doing great, but got a little carried away and had a run. So after it dried I attempted to san out the run. Again, I got a little carried away and sanded through the CC and the BC to the primmer. So the question, can I simply spot in the area that is sanded through to primer with the BC or should I recover the entire area with color and then the CC again. I have wet sanded the entire panel so I can do either.

BTW, too bad I got a run, the panel looked fantastic!!!! cept for the run.

Dr, you can just put color on the effected area and then clear the whole panel. Be careful that you don't apply the base too wet. When ever you break the surface of the clear you run the chance of solvents getting under the clear and lifting. So take it easy and don't use too "hot" of a reducer. Then let the base dry for a good few hours before you clear, just to be safe.

Professor you can just spot the base no need to re color the whole part just enough color to hide the primer spot. One your first coat just cover the primer, then on the next coat go about two to three inches past the primer, continue outward til you cant see the primer spot. This is what you would call a blend it is gone every day in the body shop, if you painted the whole part you might not get a match. Once the base has flashed off or dry reclear the ENTIRE panel you cant just spot in the clear.

Dont use wax and grease remover on the sanded base coat you can lift it just use clean water to remove any sanding residue before you color the part. Also go light on the color that too can lift if you put to much on...Eric

Now that you can fix the fix. Next time you have a hanger (run). Let it se3t up and then the next day Shave off the CC run.
Take and new straight edge razor and bend it between your two hands ,and form a arch of a few deg.
Now look at the run/hanger just as you would a damaged panel.
The run protrudes above the surface and the razor works to SHAVE the CC flat.
Examine the run and do a cross hatch attack if possible. This is LIGHT preasure like draging a blade accross you fase.
you'll be able to see when it's getting level with the surounding panel. The blade will start shavein off a not just the run but the surounding area.

IMO if you try sanding off a run 8 out ot 10 times you'll sand low spot or through spots adjacent to the high build Run.

Wayne, I have been in this business since before there was ANY of the cool run tools, even before there was paper finer than 600. I have tried them all, NONE worked very well. The method you described is like friggin magic! I had never seen it done till I got the job I now have about a year ago. These guys remove hangers! They remove runs that are stuck in little nooks and crannies that you would NEVER get out with any other method. It really is a neat trick.

Wayne & MARTINSR DITTO again, also have had good luck with the sanding stones that are being sold. Professor_SS- As Wayne said, key on both is to insure material is cured to the point that it doesn't still have gummy texture in run. ALWAYS take your time, don't rush this process. Karl

thanks guys, I'll give it a try next time I have one. I just don't seem to be able to get the hang of CC espec on a vert panel/surface. Also, it seems that I have better luck when the temp is down around the mid 80s. It has been very hot here and the hotter it is in the garage, over 90 the other day, the more I run stuff.

Hows your light ? CC in a dim lighting is hard to lay on. Vartical panels have the laws of gravity to over come.
Martinsr Piant basic is golden
The pros get hanger/runs and some times closets ( many hangers )on a panel.
Parctice parctice paractice and you still have bo-bo's.
