This is a bench I’m working on for my Chawk.
I’ll be fairing with Totalfair.
Do I need to sand the glass smooth before fairing ( no shiny spots)
Thanks

depends. if you added wax to the resin, then yes

if you didnt add wax, and the resin is still tacky, then no.

So, if I didn’t add wax, sand down the high points ( like the pic), wipe down with acetone, then fair?
I did add wax on the bench, so I will sand down till smooth
Thanks
