    Are there any tips to repairing scratches in the bottom of my SUV 17 besides matching the gel coat?

    I like the wax paper technique for dealing with scratches and chips.

    Clean out the scratch or chip with soap and water, let dry.
    Scrape out any loose or oxidized gelcoat with a sharp tool.
    Vacuum clean. Mix enough gelcoat of the matching color and hardener
    to fill the chip or scratch, then fill the damaged area with it
    to the same level as the original finish. Then tape a section of
    waxed paper tightly over the repaired area to smooth and cure the new material.

    Brett, thanks for the info. You are a wealth of knowledge. Just out of curiosity what does the wax paper do?

    All learned the hard way by having to fix my own foul-ups.  :cool:

    Wax paper allows the gelcoat to cure properly
    and provides a smooth finish without sanding, if done properly.

    A clear overhead projector sheet works better if you can put your hand on one. The thickness makes a better press and the inherent static sticks real nice to the hull and really feathers out the gel coat nicely.
