Hello everyone,
I was hoping to get thoughts on using single stage paint on my jambs and trunk area, and then doing the exterior in BC/CC. I was wondering what everyone else does? I was hoping to spray the jambs and stuff now, and then spray the entire car in the spring when the weather is more cooperative to roll the whole car out.

Otherwise I would have to leave the doors and trunk off the car to spray the whole thing at once. I am worried that if I do that, I may get variation in each panel if I have ever panel hanging separately when I paint it. Maybe I am over thinking it.

I am probably going to use twilight blue. I was going to go with a non-metalic porsche color, but it looks like I wont be able to get a code for it.

How do you folks tackle jambs and the like?

Thanks for any opinion or thoughts. Feel free to set me straight. As usual the internet has so much info that sometimes I overthink it all.

Regardless of the worth, I appreciate the both pennies.

 

Hmm ... interesting question. I had assumed that everybody uses the same thing on the jambs and gaps that they use on the body. I'm pretty sure the factory did.

 

I am sure they did, it just seems like extra steps in the case of those areas if using a bc/cc. I guess I assumed people spray them seperately. If I spray them all in 1 step, then it wouldn't matter. I just thought I could spray jambs in single stage, then put things back together, then spray the 2 stage on the rest. I guess I assume that most people not doing a color change don't even spray the jambs etc.

 

I didn't change the color of my 71 Olds when I painted it and didn't spray the door jambs or trunk. I sprayed SS but I've heard BC/CC is more forgiving to the novice painter. I don't suggest using different paint on the door jambs or trunk. Especially if it's a different brand/formulation. Sometimes paints don't work well together and if you're spending the money for BC/CC there's no need to cut corners.

 

I was thinking the same thing as I overthink everything lol , I thought I would use single stage for the jambs and bc/cc for the rest, I sprayed firewall , supports etc in single stage ppg in semigloss black not 100% correct as it is shinier than it should be but I think it’ll be much better to keep clean. I received the same advice use the bc/cc for all , I am planning to shoot underside of hood and back side of fenders with the aforementioned semi gloss black, but will bc/cc the underside of trunk lid. It’s so much effort to get this far, why take a short cut, Just my 2 cents as well

 

I would use the same paint on everything if for no other reason to eliminate a variable.in a color match. The skill level required to shoot a single stage metallic is higher than that required to to shoot a base / clear system. The later is more forgiving in that you can literally just fog the paint on the surface on your last coat and then cover with clear. With single stage you need to control gloss level while maintaining consistent metallic coverage. Much harder to do and novice painters can easily end up with striping and or mottled metallic.

As far as shooting the car in pieces goes, Pros do this all the time. You must however maintain strict control on air pressure and temperatures. Also maintain the part orientation that it will see when installed. Example, don't lay a door flat to paint it when it installed mounted vertically. Metallics may lay down in a different way than the panel that is next to it on the car.

I am certainly not a pro so I would shoot he jams and then reinstall everything to paint the car. Another advantage of this is to avoid damaging your finished paint during panel re installation.

good luck,
tc

 

I am about to do the same thing. I plan to spray my jambs and rockers in SS and let the paint get out onto the quarters about 6". I will paint the doors on a vertical rack at the same time. This is a solid color so no metallic problems. Then when I paint the rest of the shell later I can tie into the paint at the jamb crease - easy to sand and polish out the cold joint there. (This is a 70 GTO btw)

 

You could paint the jams and said pieces in two stage but just don't shoot the clear. Then assemble and paint the rest at a later date as you mentioned and/or clear it all together at once in pieces.

 

Deltron DBC has a window of 24 hrs to get the clear on it, or you have to scuff and re apply the base. According to the P sheet

 

And BTW my cost for color, hardener and reducer for 7 sprayable quarts of Concept (Deltron single stage) was $1400 YOWZA

 

I have experience with pretty much all the low budget systems capable of mixing both base and single stage qualities. What I have found is that there can be great inconsistency between the color formulation of the single stage and basecoat qualities. You could mix the single stage and the base from the same code on the same system and get two slightly different colors(sometimes a little more than slightly different). The reason for this is that metallics, pearls and even some solid pigments behave differently in one application quality than they do in the other. On the occasion that I need to do something like mix a basecoat to match a single stage job, I will pull the single stage formula and add those toners, then add the appropriate amount of base binder, activator & reducer. This is something that most paint distributors are not going to do for you, but we can since we mix in house and are very familiar with the systems. Actually, most paint stores don't really know much about the use or application of their products in the real world. They just know how to mix and pull tech sheets as far as they were briefly taught in a classroom.
