Rubberized undercoating over rub rail

[JasonBewley]

I read an article on using using paintable rubberized undercoating over rub rails to better seal the hull deck joint. Has anyone tried this? Does it hold up well, or crack and peel? I assume it would have a course finish even.if painted. Would it be considered cheap insurance against a leaky joint, or just hill-billy? Any thoughts or comments would be appreciated.

Probably wouldn't use rubberized undercoating. Now Rhinoliner or Herculiner...those materials are the bomb when it comes to sealing and abrasion resistance and super UV resistance. Rhino can even be color matched. You put that stuff on however, and no chemical stripper is going to ever take it off, you will be sanding/grinding to remove if you change your mind later.

Found an epoxy blend called Gator-Guard that looks perfect for this application. It comes in white, has the elastic & adherence properties of epoxy, but is blended for UV stability. Permanent indeed; I better remember to replace those screws with thru-bolts BEFORE its applied
