base coat adhesion on all jambs after final body sealer/base/CC (new body paint, seasoned jamb paint)

[fairlane292]

Funny you should say that. Jambs are one of the first things I look at, as do most of my customers. Door hinges too.

I am very picky and though I've removed hinges and hand polished them along with much of the jamb areas (and there are many panel-seams and their jamb areas [jamb areas: doors jambs, inner door surrounds, firewall, inner front fenders, trunk, inner hood surround, inner trunk surround]). I've only painted one complete car in base/CC and that was panel painted since it was a solid color, so I've never sprayed a body with panels in place, when jambs were already completed. Since I really want to do metallic next time, I need to do this. With all the info the experienced and professional painters here have provided I should be fine with my 600 body sand of the 2K primer and light 800 or 1000 or gold pad on the very small edge in the completed jamb areas where the base (with activator) will land up to the foam tape. If I plan it well the 2K primer will likely be less than a month old.

The '61 Fairlane is a BIG car, thankfully the roof can be done independently and mine is 2 door.

If I had more space, more help and more experience I'd consider John Glenn's "shoot your jambs with base then loosely assemble the panels so you can walk the length of the car when shooting base for even color/metallic orientation, then pull it apart and clear everything separately."

I used to be afraid of panel painting metallics, but I've gotten away with it so far. As long as it's the same paint, same gun, same PSI, same painter, and as close to same environmental conditions as possible, it seems like in my case the stories of matching problems are overblown. The biggest problem is not having the paint mixed well enough but the brand I use does not have settling issues.

You might want to test it by shooting small test panels on different days and see if they match. I am guessing you might be surprised.

All I ever do is panel paint. I don't know, maybe I'm color blind and these cars I do are rainbows... Not sure. I had one issue one time that I can remember and it was definitely a self inflicted wound.. I knew better and I sprayed some parts (636 switchblade silver) when it was well over 100 degrees in my garage.

I used to always cut in and then paint the cars complete until the shop I worked at basically forced me to panel paint.. I painted parts months apart from each other and never saw any issues... heck, I panel painted tri coat cars... I was super stressed about it, but no problems that my boss ever brought to my attention and he was extremely critical.

Someone suggested on this forum a while back a tip that I never thought of and I intend to use on some of these higher end projects Ive got coming up that need to be sprayed seperate. Someone suggested when you have a gallon (for example) of based mixed, have them seperate it into quart cans, that way theres less chance of inconsistency down the road once you start using it and it starts to settle. Im not good at explaining.

Rookie here but if I have left over basecoat that is RTS I keep it in a jar....next time I paint I mixed up some paint and pour the old with it and just keep doing that not sure if it does anything but it makes me feel good
