Mark Lindell of Wilmington, DE had a rust problem in the rear window of his 1970 Cutlass and purchased our RustReplace.com 4-piece rear window channel repair set to resolve it. Our rear channel set for the 1968-1972 Olds 2 door hardtop covers the quarter and roof channels and Mark did an excellent job installing them. Mark is now moving to the windshield and will be installing our top channel set – please keep us posted on that install!
