When it comes to the end product preparation is everything, that is why we spend more time sanding, patching, painting, sanding, cutting, patching, then painting again. This time we saw a lot of imperfections in the paint that were not corrected, we had dirt in the paint and drips all over the place.
This was fixed by sanding the paint back down to smooth using 100 grit sand paper by hand and with 120 grit using an pneumatic dual-action sander. This method made quick work of the issues and also chewed through the fiberglass Bondo we used to patch holes. Check out the video below for a speedy version of how we did it!
