So on to the rust I knew would need to be addressed, not for MOT reasons, but rather for waterproofing and because I knew it was there.
So I undid the sill plate and removed that and folded the 40year old carpet and underfelt etc out the way after removing the door seal and rubbers.
Closer inspection showed that despite my expectations, it is another as bad as expected.
Clearly not a desert or new car.
Felt my butt being nudged and it was security cat wanting to inspect, Harley, she has always loved a new car and has to check them out.
Found some good fresh steel plate in the C10 cab, then washed the floor, scrapped and poked and actually hammered the rust before drawing music lines out where I felt the new metal needed to be let in.
Cut and measured the first replacement section.
Offered up.
Further cutting and shaping to get the angles and fill right.
Only good metal to good metal.
Edges on both sides of the patch panel cleaned up, ensures a much better went.
Then grind back the paint and rust on the floor in preparation for transferring the patch panel pattern.
Also some Vactan planned for the pock marked shallow damage.
Some welding and some rust converter planned here, worked well on the C10
Next up will be transfer of the pattern to the floor before cutting the rot out, followed by welding and primer.
