So I replaced 2 brackets for the swim platform. I used the quick dry 4200. Had to cut the old brackets off the stainless rail. Then used the funnel type thing that screws on the tube so i could get the holes filled up. Last hole the back of the tube blew up. Now 4200 all over my hands and tools. I coated the bolts in 4200. Hope I got enough on them, I know I had enough on my hands and everything I touched!
