HELP what am I doing wrong

[jcnelson]

I’m trying to put a new roof skin on, I’ve watched the video of clamping and glueing ok but the fit up I can’t get right. If both corners align the center is a mile off, one corner and center the other corner is a mile off. I have tried everything I and think of short of removing the seam along the back.

You may have to fit the corners and tack in place. Then work you way back and forth to get the center.

[jcnelson]

Ya tried that, the middle is 1/2 inch up. For a repop this one is the worst I’ve had to work with. Even the doors where a better fit

[camtoys1]

do you have any pics of how the front is fitting

[jcnelson]

No, the front and sides seem to be aligning fine, it is primarily the back seem

[camtoys1]

you can take a hammer and dolly and get the end or center to come out and fit better

[camtoys1]

and it looks like the bow is wrong on the panel you need to get it to fit better in the rain gutter area and work on the middle

[jcnelson]

That is my problem the center. The rain gutters seem ok maybe a bit over size but not binding or pinching. The front has lots of room to move. I’m almost thinking if I cut the rib out of the skin to relax it then weld vis glue

[camtoys1]

take some pie cuts out of the back edge that goes down the back side and see if it will let the middle bow more

[jcnelson]

I did do some which make the corners fit better, it almost seems the center is to long about 1/4 to 3/8 an inch making it bid

[camtoys1]

you can take hammer and dolly and reroll the edge in the middle to make it move ends move back

[jcnelson]

Hadn’t thought of that, seems that will tricky, that’s a very defined curve

[camtoys1]

its aftermarket panel you have to work it and the seam sealer will hide some of it or you can take cut off wheel and slice it and move the center in and weld it back together

[jcnelson]

True, except this is the body line which runs side to side so no seam sealer

[camtoys1]

you have to use sealer to keep water out that's how it came from the factory all long the back edge

[jcnelson]

Well I was planning on welding it and use short hair fiberglass bondo

[camtoys1]

if your going to weld it a cross the back you can just cut the back edge off in the canter and weld it and that will let you get the out edges to fit and your done

[jcnelson]

Well that was what I was thinking, I wanted advise and ideas from guys that know what I’m dealing with. I do appreciate all the inputs
