Basecoat spot repair question ?

I was scuffing up my doors so I could re-clear them on Monday. I notice that at the bottom of the doors I was a little thin on my base (dark Blue). I also sanded out a run and got into the base just a little bit but enough to make a color difference. When the water is on the door during wet sanding the difference is visible and I thought this might be an indicator of how it will look with clear on it.

Can I spray some color on the bottom edge of my door and on the spot where I sanded out the run and then go ahead and re-clear? I don't want to spray color over the entire door again but just do spot repair. Is this the way spot repairs are usually done?

Will the repair hide with the next couple of coats of clear? It has been two weeks since I sprayed the base coat and clear. I used 800 and followed up with a gray scuff pad.

Thanks for this site and your help. It has be invaluable to me in learning how to paint.

sand the area with 400 or 600 your choice... and then spot in the base as you have said and re clear the whole panel... it is done everyday... NO big deal or worries mate

I am assuming you have already applied clear and have sanded through to the base.

If you have already applied clear to it and then spray some more base over the area then reclear just that area you will be able to tell it. There will be a light refraction differance. It is best IMO to scuff the entire door, shoot a coat of base over the entire door then reclear.

Yep, your fine. Your clear should cover that 800 scratch easily. Like BK said, you can sand the area you will be applying more base with a little courser grit. Spray till you have coverage then blend the base out a little ways. After proper flash time, clear the whole door. You may want to be a little carefull with the first coat of clear, it may wan't to run easier if you put it on too heavy, without having base to bite onto and only having mechanical adhesion on a 800 scratch. Once you have the first coat of clear on, the second one you can spray a little wetter, and make sure you have no dry areas.

Thanks for everyone's help.

I touched up the base and shot my clear today. This time I upped the air from 23 inlet to 28 because I got some runs last time and what a difference. Attached are the results.

Vince, if you have blended color over the clear but not the entire panel and then cleared the entire panel and you could see the base blend, you did something wrong.

As BondoKing said, this is done every single day in bodyshops around the world. It is a standard blend that is one on six to ten cars a day where I work. These late model cars, some brand new Toyotas that have never even been to the dealership yet.

The only experience I had was with a silver lacquer job. The hose came into contact with the quarter panel as the clear was being applied. The spot was sanded down to the base. A little base was reapplied in that area then recleared. You could see a color shift in the area in bright sunlight. Must admit I have not run into the problem with BC/CC. Sorry for the confusion.
