how is touch up a pain? you shake the can, pull the top and press the button......20 seconds later, you invert the can and spray until it sprays clear.
If you wish, there is an aussie company that makes a full body boat motor cover.Sorry, amerian company .So in actual fact chips are no longer the cost of doing business if your willing to pay.Looks like approx. 300 for your motor.http://outboardcovers.com/usa/custom-outboard-covers/full-covers/
Actually the chips happen on the gravel roads I occasionally travel but the deep water tip is a great idea. talked to upholstery shop they will make me up a snap type for $150.
Problem solved. Thanks for the Aussie info. Interesting.
