The two products you mention are thinner, more like a mastic product. If you need something thicker and more like a putty try: Z-Spar A-788 Splash Zone. I don't know how they recommend removing the Wet/Dry 700 or the Quick Fit 2300 but Splash Zone can fairly easily be removed with a heat gun (when it comes time for the patch removed and the repair to be made). This is important because if you are looking for something as a temporary repair (to get you thru til you can make a proper repair) then being able to easily remove the patch is a definite benefit. Not that Splash Zone cannot be a permanent repair.
Hope this helps, Good Luck,
