07 Silverado Rust Belt Damage Repair

[rcsbls2]

The time has come to get to work on my DD. bought new in July of 2007, lowered and added wheels within 1st month.

Driven Daily now for 8 years and about 100,000 miles. For the winters I take off wheels and go back to stock 17" that came on it. Actually the front spoiler pushes snow sometimes! I watch for frozen chuncks and debris that might take off spoiler / deflector.

So in the last year I have begun to notice a few spots of rust starting and progressing.
First and worst is the tailgate.

Bottom seam is really bad and now has small holes in outside on back.

Area above passenger rear wheel is coming through at this point.
