Fixing loose screws in Canon EF 28mm 1:1.8 USM

Fixing loose screws in Canon EF 28mm 1:1.8 USM is easy, just take off the bajonet , in this case there where 3 screws inside that hold the lens housing. I use just little Locktite 222 (purple color) light screwlock on each screw, so it will not easely be loosen again. And also on the screws for the bajonet.
