glass repair questions

[dcobbett]

I’d like some help regarding basic glass work.
This is a picture of a couple of dings in the edge of the fuel cavity cover that I’d like to repair. There are several others just like these around the edges of the cover piece.


I assume I need to sand/grind it down a bit to fair it out and expose a sound glass surface, then wipe it clean (acetone?) before I start to build it back up, correct?

On the build up, would I start with cloth cut to shape, followed by a paste filler, then a fairing compound (if needed) then Gelcoat, or skip the cloth and go right to the paste filler, fairing compound, Gelcoat, etc.?

I’m planning on doing small projects like this in my cellar and smell/odor is a major issue.
The last time I used regular resins (20+ years ago) they stunk; still the case?
I’ve used MAS epoxy building a couple of small boats, and odor has not been a problem.
Are other brands of epoxy odorless as well?
