Hello When replacing a fire door gasket, does it look nicer to clean and grind the metal bracket that holds the glass in? A little more work but nice results? Ripped out the old gasket and cleaned out the old reddish orange silicone with a wire wheel & flat blade screw driver, then masked with masking tape. I also masked the rope gasket channel so the new gasket will adhere better. Pic 1 - wire wheel rust & dirty carbon and ash. Pic 2 - grind real smooth with a HF $15 grinder and flap pad. Pic 3 - spray paint with high temp Stove Bright Satin Black Pic 4 - after 2nd coat for good coverage Pic 5 - apply the clear high temp silicone Pic 6 - Install high quality graphite impregnated 7/8” diameter rope gasket. I always start in lower corner near door hinge. Pic 7 - clean glass with single edge razor blade and Rutland white off glass cleaner Pic 8. - Done with nice rich and smooth black glass bracket & new door rope gasket.
