Fixing dings under the boat.
 

Does anyone have suggestions for a type of repair techniqe to fill in all the little dings from loading and unloading on the trailer and some beach landings.

Not too serious stuff, Marine Tex.

You have to grind it clean and use Interlux Watertight Epoxy Filler also, one of the best product I use during my restoration to fill in some of the gouges I found at the bottom of mine and the razor V ...

Does Marine tex have color to it and can it be buffed to somewhat shine like gelcoat?

I am not sure, but you will need to apply Gelcoat over any filler you applied, and buff it its not hard to do at all..

Marine Tex has White and Gray to choose from.
This probably will answer any other questions.
