i have rust on my floor board around the passenger side outter rear seat bolt area ... that is already going through.. i want to just do a scab patch and weld it .. and cut out the rust ... being that its covered by carpet and no one will see it ..
my dad is a welder and said get all the material and he will do it what thinkness of sheet metal to used
1/16 .. 1/8 etc

and will it be structurally sound enough to withstand corning and twist from going side ways when i go into boost
