floor pan questions

[colonel mustard]

hey all....so this will be my first floor pan job and I have some questions and my searched are yielding conflicting results.

1. do I cut the floor smaller than the floor pan patch? if so how much?

2. I was always told to weld in the new floor pans, which is no biggie as I'm a welder by trade, but now I am being told that the "new" is a body glue. sounds too good to be true. so which way is better?

3. good sources for the pans? so far I have autometal direct...any experience with them?

everything I've bought from AMD has been very nice stuff so far

I have never heard of body glue so I would just stick with good old fashion welding.

My brother works in a body shop and they use the glue to install exterior body panels. He says to stay away from the glue on structural panels. So I too recommend welding.

If you own a welder then why not weld? The panel bond adhesive gun and the adhesive are added expenses. I would also suggest that if you do glue, take notice on the outside facing part of the panel to seal the lapped over area of the repair very well from moisture.

Also, if its a large structural section of the pan maybe welding would be a safer bet.

mostly because if technology has changed, and a new glue was suppose to be better than welding (which I found hard to believe), then it would be nice to know and maybe try something different is all

cool...that's what I suspected....but the way technology changed I figured it wouldn't hurt to ask.

Oh for sure. I read an article in hotrod magazine(i believe) and they used panel bond on trunk pan extensions. Then they undercoated it to match and you couldnt even tell it was repaired.

If you're a gambling sort of person, go glue.
We're talking about your safety here, so I would go the welding route.
I think the floor pan is more of a structural piece. If not structural, it holds the structure in key places.
Think of all the flexing and twisting.

I'm no expert but I had to go through this and welded.

Stay away from glue. A friend that's been in the auto body repair business 30 years recently sent me this.

A 'BUSINESS' decision. Not a 'good common sense' decision. Profit before safety.
