Use weld thru primer.

What prep work is necessary before I cut & install a reproduction
patch panel? I'm thinking that I should at least prime the backside
before I install it. So before I do, seems like I ought to wash it down -
WITH WHAT? and then go over it once with 80 or 120 grit sander. Would
treating the bare metal with some type of ospho metal prep HELP? OR HINDER?
I know that I will need to remove the primer from the immediate area
where I will be welding, how far should I strip it back? I do have
weld-thru primer for the stripped areas. Thanx again.

Thank you both. I know of the glue on method and have always thought
that the special application gun would make it too expensive for a one time
use. I'll investigate. And I know that a butt weld is preferred but I'm
not sure that I could manage it over the distance. I repaired the
floor with a butt weld and had to buy a second panel because I screwed up the
first. But I took a good look at it all this AM and the inner fender well
is needing significant work too. Maybe by the time I'm doing the outer
quarter I'll be more proficient.

This is me personally on the matter, I prefer to butt weld my panels for
the simple fact that in my mind lapping the panels makes a new place for
rust to form, that's my personal take. If you are still going to lap weld, lap
the original over the new, and make sure to drill plenty of holes to plug
weld. Also be sure to stitch weld up your seam where the panels meet. But
think of this, if you were to butt weld your panels you can clamp the patch
over the old and use a die grinder to cut off your old panel and you are
also cutting the patch to fit all at the same time, then all you have to do
is clamp and butt weld the panels back together. You should have no problem
welding at the trim line that you want to use and like you said the trim
can help hide any faults, but if you work at it you can get it dang near
perfect!!! As for the spot welds I use a 5/16 - 1/4 Rota Broach, its pretty
much like a spot weld cutter I bought mine from Snap On a few years ago,
Blair also makes them. But in a pinch you can drill a pilot hole or just use
a punch to center it up. Hope this helps.

This will probably be the first of many messages as I attempt to repair
this
_http://www.chevelles.com/showroom/showphoto.php/photo/21067/cat/500/ppuser/1865_
(http://www.chevelles.com/showroom/showphoto.php/photo/21067/cat/500/ppuser/1865)
. I have a patch panel that goes as high as the
tape. I am cutting off the entire length because the inner panel is rusted
also and there is no way that I would be able to deal with that thru the
holes I have cut now.
First question - Where should I cut the panel. I'm thinking (dangerous)
that I only need to go as high as the body line located just below the
trim rivets. I like that area because if I do a less than perfect job,
it will be partially hidden by the trim.
Second question ( or statement) - I am going to flange and overlap the
top seam. Should the new panel lie over the original or should the new
panel be tucked under the original? Does it matter? I can get to the
entire backside of that seam thru the access panel in the bed and should
be able to seam seal it pretty well.
Third - any hints/tips on drilling out the spot welds along the bottom?
I bought a special drill for them but my first attempt resulted in the
bit walking. Should I drill a small pilot hole?
Thats all for today. Thanx
