Windshield installing companies seal windshields in place , I believe, just
as you are talking about.
Might check with a few.
might be worth a few bucks invested.

you have the right idea about lifting up the rubber ...etc.

if you don't want your sealant to stick to the painted surface on the
outside,
but a thin film of something like vaseline there, as a separating agent..
and the sealant won't stick to the paint next to the rubber seal.

if it's rusted or rusted through underneath the rubber ..
it might take a 'real' ..remove windshield, new rubber seal, reinstall, etc.
