Weld thru primer applied to both pieces before welding, paint and seal after.
nearly every car on the road has spot welded floor pans sills etc
and then theres the problem of galvanic reactions when using ally floor rivetted to steel chassis.
after a period of time the ally floor could fall off as the rivets corrode and eventually disapeer
my floor is steel welded on as above
other people have rivetted ally floors and theyre fine too
if you have the steel weld it on im sure it will make an excellent floor and cost nothing.
many kit producers also weld in floors im sure theyre not all wrong
