modifying the tail...

[absintheisfun]

Does anyone have any pictures of anyone who has filled the crease between the rear quarters and the tail? I'm thinking of doing this to "smooth" the rear on my 67 Camaro, but I was wanting to see how it looked before I did it.

Any thoughts?

thanks

Marquez designs did this on Jonhny 69 Camaro. It looks outstanding! You can see pics here: http://www.lateral-g.net/forums/showthread.php4?t=6562

That does look pretty slick, but it looks like he filled the crack between the trunk and the spoiler. I was talking about the crease that runs on the side of the tail piece...anyone ever seen this, or tried it?

I did it on my car with seam sealer and have had no problems at all so far, the car hasn't been driven but it has gone through temperature extremes from 40 degrees to 90+ degrees F.

I chose to use the 3M seam sealer that was sandable. I applied it in an over abundant amount and let it sit for a month and then trimmed it in with a razor knife and let it dry more before I touched it up with another layer to be trimmed where it needed it. Then I applied DP90 epoxy primer and let it dry for a week and then sanded it with 150grit sandpaper until it is the perfect shape. You need to look at it as shaping it. You can also get better results if you dolly and hammer the area on the rear quarter that mates up to the tail panel to match each other, most don't match exactly but can be shaped to do so.

I will get a pic for you and post it.

It really does become noticable when they both match when you are looking for it and having it smoothed it perfectly takes some time but is worth it.

My body work experience is low, but why use a seam sealer? Why not use a filler of some kind? Will it crack and fall out?

The first time I did mine I just loaded up on filler. It looked good but I know it would have all cracked apart.

After I started re-repainting my car I scrapped the whole filler idea and welded it as best I could and am doing all the filling in lead. But my car is a total hack. Trying to build it without much money. I have to fill it because it had new quarter skins welded over new quarter lips welded over original lips. I tried to remove as much as I could and bridge the newest to oldest parts but you know how that goes.

Here are a few pics of what it can look like with seam sealer if you have the time to let it shrink, and it all shrinks even if it says it doesn't. The nonshrinking just shrinks less.

The reason to use eseam sealer is because of the expansion and contraction of the parts as you already know ,but the other is the tremendous flex an F body puts on the rear panel where it comes together. Unles you lead it or weld it the paint will eventually crack a line. If you weld it you will make the metal more brittle than it can take and it will crack everything and then you really have a repair on your hands. I spent a lot of time researching this and found that seam sealer is the best way, and having patience to work with it can make it look like great. If you look at the lower part below the bumper you cant even tell and it is just sealer.

You have to remember that there has to be some kind of line to divide the rear panel to the quarter to make the blacking out of the panel work out if you want to and it also is the way it was designed to look right.
