[68Timber]

I've got the glass out and my old seal off but there's a ton of sealant to remove. What's the right way to get this stuff off? Scrape or wire wheel or ? I've got a little rust in each bottom corner that needs some rust converter on it but I don't want to go all the way to metal on the rest of it if I don't have to - this is a rattle-can repair on my military Blazer.
