Paul,
Prepare the mating surfaces by grinding them with a 36 grit disc, blow
off the dust, apply the primer supplied, let dry, apply the body panel
adhesive, clamp panel tight, walk away from it.
Let it sit overnight, remove the clamps, your done.
Be prepared to work pretty fast, this stuff doesn't set up right away, (
I think working time is about 15 minutes ) but you ever saw time fly so
fast.
Have everything fit, aligned, and know what exactly your going to do, as
soon as you lay the adhesive on the surfaces,
have the clamps all arranged etc.
