Re: How should I fill firewall holes

nuthin wrong with that, it cleans it up really nice, as long as it doesn't rub or rattle it's all good.
your truck,your idea, you're good with it. thats what counts.

Re: How should I fill firewall holes

I wanted an overall clean, smooth look so I did a steel overlay. As the pictures show, no welding was involved. I resisted "gluing" them on but a couple experienced bodymen convinced me that it was the way to go due to no warpage and minimal finishing associated with the process.

Fitting poster board templates



After prepping I used 3M panel bond adhesive to attach the 18 gauge sheet metal panels.



Edges beveled and blended with filler.



Primed and painted...



I'm really happy with the end result

Very cool. I like the edge blending around the firewall cut out. I was planning on doing some work last weekend on mine and ended up slicing my hand open drilling some sheet metal.

Life lesson: Don't hold onto a stationary thing while using a spinning thing.

Re: How should I fill firewall holes

If you know an electrician with a toolbox, he probably has a whole bunch of 1/2", 3/4", and 1" KO punch outs from metal boxes. Those work good too for larger holes. or just buy a few metal boxes from HD or lowes and take em out yourself.

Also roofing nails work good for small holes - they have a BIG head....

Re: How should I fill firewall holes

it is just plating so you could always sand/grind it off if you need to.
