I purchased the tape, but I am considering drilling and taping holes for set screws and loctite the set screws. From what I have read no one has not had an issue with the double sided tape, but I'm sure vibration over a long period of time will cause the rack to come loose. I have also considered welding some small 1/"2 tabs ever 6" or 12" and using machine screws to bolt the rack in place.
The reason I asked is someday I might face the same problem,,,not sure if you can drill & tap,,,don't know the rack's RC value,,my self I can see me epoxying the rack to a wide piece of flat bar and drilling and tapping that to the rail

If you are going to try to take out that 3/8 bow,,you might consider a hacksaw cut at the bow middle and hammering or jacking it into position and rewelding and grinding,,,not a pleasant job,,,heat at this stage of the game won't do much,,,,,could position a timber along and/or above the rail to give you some thing to jack against....just a thought
