I thought about it but elected not to spray the bottoms... the jack feet are unpainted on the bottom so some rust might occur underneath, however, the snappads fit very tight at the lip and now the drain holes work well so nothing I'm going to worry about.
Very nice look. Did you spray the bottoms too ? That will look sharp with the Snap-Pads on there.
If it fades in a few years spray it again.
FYI: On the "Holy Snap-Pods" They have been draining right out and drying up, and seem to be staying cleaner now too. Glad to see a lot of you have done the mod and got them installed. Now it's time to push the "Auto Level" button, sit back, relax, drink a beer, and watch the guy coming in next to you in the campground going back and forth trying to get his trailer level without too big of a smile on your face.
