Have some spots that need touching up due to dents or rust.
Base / Clear
The paint is metallic, but not faded.
Some spots are low enough that nobody will see them. Could I use a single stage on those? (I have a pint)
Others will need the B/C.
Don't really want to do an entire panel.
How do I do that?
Thanks

What parts are you doing? If you are doing a door or bed side then youll want to blend into the old paint with the new.

Lower door panel and a rocker.
The "blending" with the B/C has me stumped.
Do you sand the entire panel and blend in the base color using an arcing pattern with the gun - and then clear over the top? Is it okay to shoot BC over existing clear, even if it has been scuffed?
A better way to phrase my question would be -
How do body shops fix door dings_in a panel that has been shot with B/C?
To add to the mix - Can I use a single stage over the B/C if it is in an isolated section?
Hope I explained this correctly.
Thanks

you could shoot single over scuffed b/c, but it will be difficult to blend, especially metallic... but you can clear coat the single stage, might help... then have it buffed out real good by someone who knows what they're doing and you should be ok...

this is assuming no fade of the original as you claim... I would do a test spray on a piece of scrap and then hold it to the truck to see how it looks....

Hold the boat here, you guys are making this much to complicated. Blending bc/cc is very, very easy. It darn near does it by it's self.

First off, you want to CLEAR the entire panel when ever possible. There are many ways you can stop at a body line, but we will skip that right now.
You clean the entire panel, let's say it is a fender. You would do prep it one of two ways, with a gray scuff pad wet, gray scuff pad with scuff gel (my choice) or 1000 or 1200 paper wet. You would scuff or sand the ENTIRE panel until it has a nice uniform sheen with no shiny spots. Then, after THOUGHLY cleaning, masking and tacking, you shoot your base. The base is shot over the primer spot (sealed sometimes, that is another issue) and "blended" out. Yes, you simply let off the trigger as you go out past the area with a waving on of your wrist. It is kinda basic sense here, you don't want any patterns, but a nice "foging" out of the paint into the surronding area. You then clear the whole panel. It is very easy and trying to keep it down to less than the whole panel is usually a joke.

You can blend the clear also so you don't have to do the whole panel. This is much more tricky. It is done buy prepairing the blend area the same way as mentioned above and then blending out the clear in the same fashion, with the last "coat" being a blending solvent that melts the clear into the old clear.


This is not a "Basics of Basics" on blending, I have left out a lot of detail, but you get the idea. If you need more just ask.:burnout:

MartinSR, of course blending bc/cc is very easy when you're doing it with bc/cc, but read his post again.... he has a pint of single stage that he wants to use for this job, not bc/cc... this is why I suggested he do a tester on a piece of scrap so he could make adjustments.... I do agree that clearing the entire panel would probably give the best result....

Sprry Bigvinnie, this is what I was commenting on. He has questions about Bc/cc. My answer pretty much covers the idea of using the single stage. But you have a point, I shouldn't have skipped that.

The single stage will likely be a much different color. Why torture yourself with the SS just because you "Have a pint" and go ahead and get the bc color to do a nice blend and clear job.

I would scuff the whole panel. spot the color with 3 or so coats. each coat extending past the last. this will aid in the blending. Clear the whole panel. However, if your not really good at painting or buffing & the paint is a few years old I have a trick I use. I scuff the whole side of the vehicle. Spot the color in the damaged areas as stated above but clear the whole side. Sometimes the new clear will be more shiny than the old clear. This will "hide" the door repair because the whole side has the same gloss. The edge of the fender & hood might not match in gloss but it will not be as noticeable as a door to fender.....only one or two light coats of clear will be required on the NON-repaired panels. the amount of extra clear to do this will be very little. it might equal the amount that you over mixed & was going to throw out anyway. this might sound stupid but i have dont this before & totaly hid a blend. It will not give your eye one panel to look at for imperfections. I hope I explained this clearly, I'm kinda tired tonight after working my 9th "11 hour day" in a row. :flag:
