Water heater Bypass and Sanding

The other day I installed the water heater bypass to reduce the amount of RV antifreeze used to flush the system of water. However, I created a leak in another fitting and today finished the repairs of the leak. I am awaiting more deliveries to prepare it for the last camping trip of this year. I now have almost all of the primer gray sanded off of the rear f the rig, wow it is amazing how beautiful she is under that layer of paint. I will need to find out how to rejuvenate the gell-coat of the rig, as there were areas where the white had been sanded off and also there are cracks in places.
