so many different opinions on here as well as around town, im guessing it just will boil down to common sense taking all these tips into consideration. thanks for all your input.
I would have to say that it depends on the condition of the frame around the opening where the seal goes. I mean if it is in really good condition (no rust pitting, rust outs, dents, other damage) then the seal should not need sealer. I always make sure to repair any damage before I set a glass in using a rubber seal and rope. By the way, I'm sure the guy doing it knows this, but I always use dish soap as a lubricant on the rope so it slides off the seal easy and doesn't tear the seal especially in the corners. Then when you're done it washes off with water.
