For a competition car, what about just doing everything?
Cage, seam weld and fill the sill and chassis cavities with foam


As long as the chassis was clean and no rusty or other debris inside the cavities, I don't see how it could cause any problem with rust etc.
If the shell was dipped and then filled with foam where needed, it would be the right job!!!

your right your right, no cutting corners! only ting I was thinking, would it be ok to seam weld the underneath as in round the chassis legs after filling them with foam??

The Chaser's Chassis is Filled with Foam. Definitely benefits rigidity.
