Rust inside the window channel

[praisegeetarman]

I have a nearly rust free blazer that has some starting to form inside the window channel. How have others addressed the issue of stopping this rust? I thought about trying to sandblast down into the window post, but not sure how effective that would be.

Ideas?

Anyone tried these products from Eastwood?
