Guys
There is only a couple of things that you do differently with a glass body
as opposed to an ally or steel body.

First
which is a bonus you can block back the gel coat a bit so you dont need as much high fill primer. Dont go through or you will need to re gel those areas.
Second
You need to apply an etch that is designed to go on to fibreglass.
we would do this before any bog would go on.
Third
aplly filler to bad areas and file back.

Then you just approach it like a normal steel or ally body .
High fill and block
But all thes products are two pack to help resolve shrink back and the glass
moving to much. Then leave it in high fill for as long as you can before final block and colour.
Hope this helps

Regards
