I did my drip rails about 3 or 4 years ago, so I don't really have any newest and best stuff to offer you, but I will say that the 3M self-levelling sealer was great stuff at the time. I used the 3M Automix Heavy-Bodied Seam Sealer - 08308. I had to buy a special gun to mix it, at the time, the gun, 3M Manual 200 mL Cartridge Applicator Gun - 08571, was only $37 from autobodytoolmart. I think it is much more expensive now
