I know the instructions are complicated and hard to follow, so in a nutshell, yes.

How to prepare surfaces for bonding:

-Remove all rust, scale, paint and loose materials from the surface.

-Clean all surfaces so that any dirt, grease, oil, wax, etc is completely removed. (Lacquer thinner or acetone are excellent cleaners for many surfaces.)

-Sand a profile into the surface with 80-100 grit sandpaper to abrade the surface and provide a 'texture' for a mechanical seal.

-Wipe with solvent once more to be sure sanding dust hasn't contaminated the repair.

-Please DO NOT use soap! Soaps and regular detergents leave behind a residue that can cause a problem with adhesion.

Just be cautious since marine tex should be used along with maybe some fiberglass epoxied over the top as a layer. That will help in building things up.

How much build up are you trying to achieve?
