Jaegers 6" f/10 "GJD" OTA Construction - Rear Lens Cell (prepping to prime - 2)
 

Prepping Rear Objective Cell for flocking and painting - 2 (Click to see an enlarged image.)

 
With buffing to a matte finish with a Scotch Brite pad all done on this piece, I used a Scott blue shop towel to remove the aluminum residue with a paper towel saturated with 91% isopropyl alcohol.

In the case of the rear lens cell, as opposed to the front, it will be flocked flat black on the interior surfaces and also painted with the Rustoleum Hammered Finished spray enamel on the exterior.
