Is this like the seam sealer they use on car from the factory. That hard sealer stuff you see on the underside. Is that like this stuff? Trying to find something good to reseal my seems once I treat the rusty surface areas
How does a panel get spot welded when it has seam sealer in between the layers? I thought spot welding requires bare metal for electrical contact on both inner surfaces...
I will burn in that area and bond the metals.. but area surrounding it will remain intact! same with Weldthru primer! the weld will be etched on the edges and prevent corrosion. so its a 3 double method toprotect rust down the road.!
With it still being wet i assume once the panel is squeezed together for spot welding it probably disperses the seam sealer in the area enough to allow the spot weld.
With Mig Welding some are with a Pro Spot it isn't. That's why you can weld bond through panel bond and be fine vs a mig. But show me 1 body shop that does all this cause we dont.

This feels like the future.
chop shops don't do this through work. This is how you "wish" they would repair your car.
This looks like i left my car within NASA to prepare it for moon landing 👍

Is this stuff full of isocyanates? If it is can 3 m find a safer substitute I see several companies advertising 2 k primers isocyanate free.
after they talk about corrosion protection right at the end are they filling the cavity with expandable foam?
some have that as sound deadening... not my fav type either xD
If you use closed-cell foam, the foam will not absorb moisture.
What is that stuff at 3:19?

you just explained look on my face

Expandable foam.... That would not be fun to fix.
I checked with a body shop and he said DON"T DO THIS THE SEAM SEALER IS FLAMMABLE!
