Getting Ready to "JAMB" my convertable, What all to do?

Getting Ready to "JAMB" my convertable, What all to do? - 08/26/11 12:31 PM

Ive got my convertable body ready to paint the jambs and under hood and trunk areas. Just trying to figure out a good plan of attack. I wanna paint with fenders off. should i paint all the way to the outside sheet metal or stay back in aways. what im looking at is painting the windsheild frame, underhood, trunk right up to where the weather stripping glues for trunk seal so when trunk is on all under lid will be painted, door jambs to where with doors on all inside will be painted and leaving just exposed cowl area to be painted on front. Im using base clear if that matters. Any suggestions appriciated.

IMHO the whole car should be assembled, and stripped of all items not going to be painted body color, the only componets that should be jambed off the car, prior to painting, are the hood and trunklid, the entire body should be assembled and panel aligned, shoot the body/engine compartment/door jambs/trunk jamb at the same time, painted mirrors and such can be painted off the car at this time, depending on the color, your skill level, humidty, etc, etc, batch painting major panels off the car can result in shade/texture differences, best to paint the car as whole as you can, there are exceptions for each car/componets,...plus installing pre painted fenders/doors/etc always leads to that "uh-Oh!" boo boo

That's my plan... Shoot door jambs, trunk, engine bay, inside of doors, underside of hood, etc. Then hang all panels, mask the jambs from overspray, and shoot entire outside of car at once

My plans are like 70cuda383 is talking bout. I will then assemble the car and align then paint entire car as one with the hood off and door jambs masked off. I understand the color differance and probs with painting panels on diff days and such. WHat i was wondering is where is the best place to make the tape lines on door jambs, underhood and is it better to paint with trunk lid off also. I guess that would eliminate tape lines in trunk weather stripping area. Thanks and hope that cleared up my intentions.

You avoid "tape lines" by "back taping", that involves rolling the tape over on itself, so that you leave a soft edge, that you blend into later, avoid hard taping (leaving an edge), you either back tape, or you let the tape overlap the edge of the panel being jambed, later on, lets say in a door jamb they may have been jambed prior to painting the entire car, you can use apperture tape, it's like a foam cord, with a strip of semi tack adhesive on one side, you install it on the jambed paint edge, exposing just a thin line of color on your back taped painted edge, then close the door/panel/trunk lid/etc/etc/etc, it leaves the panel gap blocked off from overspray, yet allows (depending on the depth you set it at) the paint to wick in and blend softly with the "jambed" jamb, leaving you with a professional blending of the main body paint and the jamb paint, apperture tape is only used on pre jambed areas, or areas you don't want paint entering, but yet want a soft transition line of color/spray

I like to do all of them this way. No tape lines or dry jambs.

How do you recommend doing this all at the same time? Are you opening and closing the doors as you go?
The last car i did I shot in pieces and reassembled. It turned out great however I would much rather shoot it all together but I want to avoid tape lines.

And, if a car is painted without fenders installed, how does one get the fender bolts on and painted such that it appears as if painted assembled? I assume that would require masking off and painting only the fender attachment areas, but, then, tape lines?

Must be snowing in HeII, I actually agree with Dayclona!

You don't have to worry about tape lines either because there's usually nothing to tape off! Also, don't forget the body caulking between the fenders and inner fenders, etc. that got painted over as well.

How did the factory paint it all?

Short answer....not worth a sheite!

Real answer, painted all together and did mostly a poor job in engine compartments,trunks, and door jambs. Outside was decent for the era in which they were built.

From what I've seen from the cars I've disassembled, it appears that the body was assembled except for the hood, and possibly the trunk. But I believe most had the truck installed when the car was painted because the mount point didn't get painted, and the bolts were painted.

Hood bolts on a 1970 cuda I had were plated, not painted. On this 1972, however, it appears as if the hood was painted on the car...

The trunk bolts...

Oh, I also believe the front and rear valance panels were painted off the car.

A little humor and some "back-taping" education.
