So my usual steps for Duracoating parts involve dunking them in acetone and scrubbing away with a toothbrush, then hanging them to dry and spray them with acetone out of an airbrush to make sure.
But right now I'd like to refinish a scope, an old Weaver 1.5x4 Widefield. I need to rough up the surface with sandpaper as its presently gloss blued, but I'm concerned about the degreasing step. The scope recently came back from Weaver's repair shop so I don't doubt its waterproof, but I have my reservations about going at it with acetone. I'm not entirely certain how to tape off the glass portions so I can scrub away with a toothbrush, and I'm not sure if acetone getting into the power ring openings is going to eat away at whatever rubber gaster Weaver has in there for weatherproofing. So for those of you who have refinished scopes, particularly blued scopes that needed surface abrasing first, how'd you do it? Thanks. |
| I use adhesive label paper to mask off the lenses. Simply set the scope on end on top of the paper, trace around the bell, then cut out the circle and stick it on the glass. I rough up the body with sandpaper, then wipe it down thoroughly and repeatedly with a lint free cloth soaked in denatured alcohol. Works great. |
