Russ,
that is fine,but look how far you grinded metal.
was there any warpage?Plus you tack welded
the whole seam and it looks like there is gaps
between your welds.Mig welding burns off the
coating between the two metals,and that is
where the rust will start to form and work it's
way thru in time.It is impossible to get
anything in between the two metals to stop the
rust and protect it.Every welded patch I ever
replaced started rusting from the welded seam.

In my method the adhesive seals the two metals and provents warping from welding.
I used to do it that way but is less work bonding.
Welds take alot of time to grind down.
bonding there are no welds to grind.

G_T,
You can bond a whole 1/4 and align it.
you will need clamps and cleeko's to hold it
either way you do it.
Prefitting the panel is what makes it possible.
with cleeko's the holes are there to make sure
the panel goes back in the right place.
You have time to move the panel in place
till the adhesive dries. wasn't sure where else
to buy cleeko's.I use screw's, it will pull the panel together better sometimes.I did mention
using screws as an alternative.

To the rest who are negative about using this
method,Don't knock it till you try it.

Thanks,-Jeff
