When painting door jambs etc with BC/CC

When you paint jambs and hard to get to places ahead of the main paint job-and if it's a base coat clearcoat system do yo paint both base and clear or just base and clear it as best you can when you clear the whole car? My guess is just the base-because if you got some base on the clear when you painted the whole car it might cause lifting.

How have you approached it?

I'm new but from what I've seen they base and clear it. When doing the outside later, the jamps are 'taped-off' good so no paint gets in there. 3m uses the soft-foam tape that you can use to make masking the jambs easier. Thats what I'm going to do.

door jams

yes you can clear but be careful when you lay the base on the rest of the car. you have to put it on dry over the edge of the fresh clear or you can get edge mapping or lifting. also don't tape off a hard edge on the outside of the jam let the clear taper off

Sand off the excess paint that has accumulated outside the jamb before you paint the exterior and you won't have lifting problems. The most common proceedure when doing this is to get the parts in final primer, sand the jambs and paint them, assemble the car, then final sand the exterior at the same time removing any overspray from when the jambs were painted, mask the jambs and shoot the exterior.

Base and clear your jams as normal. Then mask off your jambs using the reverse tape method or masking rope. (I use masking rope in my shop) Then paint your outer shell as normal. Another option is you can remove doors and fenders and paint shell and jambs at one time. I don't recommend this way on certain cars because of the high probability of scratching the fresh paint, but it is an option. If you decide to probe that option, tip is to drill a 1/8" ref hole in panels to help realign panels and doors during reassembly and apply lots of paper and tape to your edges to help reduce possiblity of chipping paint.

This all gets even more challenging when you are shooting pearl or metallic and you trying to avoid color mis-matching if you don't shoot everything at once. Any recommendations for that situation?

Personally, I see no reason what so ever to not simply mask off the outer body when shooting the jambs to avoid any overspray lifting problems.

You start with the hole body in a single substrate color. Then you mask the body off right on the egde to shoot the jambs. After base and clear on the jambs the masking is removed and the edge is removed by lightly sanding. Then when the jambs are masked off you step it down below that edge a sixteenth of an inch or so and mask the jambs off to paint the outside.

You have basically all the ways to do this and several "issues" are involved with each method.
I lean towards Bobs routine as you need it assembled and lined up because the "adjusting" factor can wreck your nice paint work as well as totally screw the hinge bolts paint along with the hinge rollers,pivots and such.
The issue comes with painting the bottom of the shell and other hard to reach areas if the door does not open out much.
DB has about the same deal and the pilot holes drilled previous are a big help lining up but depending on work build up,some fine tuning is required. I haven't used the masking rope yet and have always back taped as Brian stated,just back or right at the edge inside on the shell. The back tape or rope gives you a soft edge and when you come back for the outside,it will melt in fine. A light scuff with a gray pad along the edge doesn't hurt either before basing the outside just in case you have some extra build.
Another issue can be using a touch up gun for the jambs and having a variance in color or metallic due to just the fact your using a different gun and applying it different. In the real world,you'll usually never notice this but for a real show piece this can be cause for concern.
As for your window,That will depend on what paint your using,

I personally use the same method as Martinsr simply because tape/masking paper and the time it takes to mask it is simply cheaper than sandpaper and the time to sand all the over spray off...And it doesn't leave such and edge if you backtape it :pimp: The only time i spray the jambs the same time as the outside of the vehicle is when someone wants an Earl Schieb :evil:
