My 64 projects drip rail is in horrible shape. After removing all the old tub and tile caulk the previous owner stuffed in there I discovered that the rail is rusted out (mainly the very top layer of metal,from the top of the truck itself, that sits in the rail). Has anyone had any luck with this type repair? I am building a driver so it doen't have to look perfect,I just don't want it to leak on me in the future. I have pulled and picked out all the old caulk and I have sandblasted the rail. Could I fill it in by brazing material in there? I am afraid that seam sealer would not work since there is such a void. Any ideas would be appreciated. Thanks, Scott
