Keep the heat gun at least 12 inches away. You can get as close as 8 inches, but you better make sure you keep the heat gun moving in any case. If you let it get too hot you will get little blisters in the gel coat. whoops. You may get a little discoloring too if you get too hot.



Try a spot not too visible to "practice" on.



BTW, Our biggest problem from denting is the occasional turning the boat over in the grass. We have Hickory nuts that have fallen from the trees that hide in the grass. These result in a nice round dent about an inch in diameter. No matter how hard you try to clear out the area or protect the hull, one of those things always finds its way under your boat.



At least they don't drop directly on the A Cats. You should see the hood of my truck from the last time I parked under those trees.
