House was foreclosed in a fire and the fiberglass kits had tons of nicotene stains and both had shower doors has been removed.

So after clean and sanding we use high end repair Filler. The secret is to take more time puttying so less work sanding. Using wet 180 grit.

We didn't have to tape which saved a little time. The savings from $2500 for replacement to avg $400 $500 why would you do anything else?
