I'm another powdercoat junkie
I got the local hot rod guy to sanblast and powdercoat it appliance white. I ,too, rarely use the stove so a year later...no user feedback. I liked it so much I had the frig shelves done in white too.
One thing I did find...the bouncing of the trailer over the velvet surface of I 75 to Florida & back allowed the elements to scratch the finish slightly. Mr Hot Rod guy re-did the top and put a clearcoat over the white. I made little donuts of white shelf gripper and sandwiched them between burner grille and stove top. (doesn't matter too much- I have a hinged stove top cover that is usually down over the entire stove)
