Detroit Speed firewall panel

[chevyshawn]

I'm trying to figure out the best and cleanest way to weld this panel in to smooth the firewall on a 67 Camaro. I've seen pics of the panels being spot welded every inch or so but never fully welded all the way around. The question is do I fully weld the panel in or just spot weld it every half inch all the way around before I bodywork it. Also has anyone used seam sealer smoothed out instead of bondo?

What do the instructions recommend?

Was a Craigslist buy, no instructions.

completely weld around the panel. Tig if you can. If your going to wire feed. small sections at a time cooling the weld with compressed air as you go.

Spot it every 1/2 inch and seal the rest with panel adhesive. I use 3M 8115.
