New Quarter Panel - Roof Seam question

[Topcat]

Got it, no worries I will just weld mine up and eliminate the issue.

all the hack work to get both panels contoured close meeting to each other without much filler variation isn't worth it.

Why are you afraid of learning how to Lead/solder?

Personally,  I think the main worry is contamination and a lack of proper primer sealer.  If this was that big of a deal,  we would see a lot more cars with crackled pillars.

Prime.   Fill.  Skim. Seal. Paint. My 70 had plastic. It was wrecked.   No cracks.  Cracks are rare.

Contamination is from lack of preparation.

You use a baking soda mix to neutralize any contaminants followed by a wipe down of Lacquer thinner and even a wax/dirt cleaning solvent.

You guys make it sound like doing Lead work is some type of smoke and mirrors wizardry.   
A couple hours is about all it takes once you get the hang of it.

Let's calm down a little here; I am not afraid to learn to use lead, if fact I have used it previously, that said I have all metal in my challenger which I painted over 10 years ago and thus far no cracks.

Bottom line; I will weld up the seams, seal them, fill them, blend them and paint them. If it cracks I will come back hear and beg forgiveness.....

I don't think it is difficult.   Just saying the seam isn't as big a deal as we are making it here, or every paint  and  body issue of hot rod would have a section on it.

so what you're saying is the factory engineers after many months of reaserch and development were over doing it?

Ever notice that all the new cars have really small ajoining sized sail panels?
Or that now they use plastic?

Go ahead and use bondo. It's your car.
Better buy a gallon to do all 6 areas.

Like I said earlier, I would fall on deaf ears.

There's a girl at work who likes to take shortcuts and it always bites us in the a$$ later.

think about it.

So what you are saying is that if you do not use lead you are completely wrong, taking a short cut, etc..?

You are right, it is my car. Thanks for the input.

Yeah it's called heat transition, heat expansion, and the  heat transfer into a different material, molecular differences in materials and how they expand under heat. Call a physics metal thermo scientist.

I've also thought of this issue.
I'm going to try the lead thing.

[TelisSE440]

That was great info... My Challenger paint is about 20 years old. I'm a litte afraid of heat expansion...

                      Does she have a nice a$$.  Just askin.

  Where is the best place to get lead filler bars?

I've seen them at my local welding shop.
Welders Supply and Praxair

When I had my 70 Challenger in the late 70's, my lead seam started to crack right at the corner of the quarter window and down where the quarter meets the rocker panel.  Since my car was originally a 318 3 speed and I converted it to a pumped up 440, I accepted it at the time.  I was hard on the pedal and the body twisted a lot.  When I did the body work on it, I did use all metal and didn't have any issues with it for the 2 years I kept it.  On the Cuda I have now, I welded the seam all the way across for safe measures since I could.  I didn't lead it though.  This site is great for the fact you can get multiple opinions.  Pick and choose what you feel comfortable with.  In the end, we are all car guys.
