New door skins

After removing the chrome molding from my 70 Ford pick up a while back I found rust holes behind the molding. So I order some lower half door skins for both doors even though I didn't need to go up that high for the small holes. The new skins, goes up to the bottom body line on the doors. I fugured that would be easier to hide the seam if it went to the body line. I was gonna weld it in to place but a freind told me to just use the sheet metal glue and then I don't have to worry about warpage of the sheet metal, from the heat of the welder. Can anyone give me some advise or tips on the sheet metal glue. Like how long does it take to set up and can I buy it from summit or do I have to get it from a body shop supplier. I already have the skins in from LMC trucks and they wrap around the lips of the lower doors. Thanks for any help guys.

Friend of mine glues on a lot of parts, he uses the Lord Fusor glue. They have both a slow and fast setup glue available. If no one locally handles it, Autobody Toolmart sells it. For the panels to join good, and the joint to not shrink he also suggests at least a 1" flanged overlap to glue to.

Thanks Dave; These lip around the door edges, the holes are very small about 1 1/2 inch dia. and at the very bottom.
I am gonna cut out around the holes a little ways then slid the pannel on from the bottom glueing it.
Then I am gonna Dura glass the top of the pannel where it butts up to the body line, then sand and paint it.
The sides of the pannel and bottom lip around the edge's.
Does this sound ok.

It's going to crack unless it's welded or overlapped with a flange and glued, Kurt......

Ok, I guess I'll still have to weld it then. Thanks Dave.

Another option would be to Flange it on the top, drill a few holes to hold it and screw it on with a couple of sheet metal screws while it bonds, and then close the holes with the Adhesive-I do like Fusor products a lot-the only down side is that you have to buy a dispensing gun (and I have the big one), although when I buy the small tubes for small jobs I just push it out with a screwdriver and mix it up-they come with the mixing tips, though

Fusor is not the only brand, but it's a good one-

LORD Corporation - Versilok® 262/254 Adhesive

I have seen alot of full door skin replacements on youtube.
But I have not seen one half door skin replacement on there.
Did I make a mistake buying the half skin instead of the full skin???
I didn't want to have to take the chrome off from around the windows.
I was just gonna cut out around the rust holes so the rust won't grow then
place the new skin over the old. I figure I will drill hole's about every inch
along the top of the panel and spot weld those to the old panel.
Then crimp the new panel along the side's and bottom like you would do anyway.
