Windshields

I also have a tube of 3M Bedding & Glazing Compound (butyl) and new gaskets too. Windshield trim clips seem to be temporarily out of stock everywhere, but since it'll be a while before final paint, I can't put the glass in anyway.

When installing the windshield, does the gasket go on the body then install the glass, or should I put the gasket on the glass and then install the assembly to the body?

I think I asked this somewhere else, so please excuse the duplicate post ;)
thanks
