I'm getting ready to clear coat it.
I use a 1/8" dowel I get from Lowes 36" long and cut a short piece, drill a 1/8 hole in a lam scrap and into the riser site window about 3/16" and super glue it in.
Well Hell, First time I got runs from VHT.
I used clear gloss and now I need to wait 7 day for it to cure, Bummer July 20th untill I can sand it some more.
