Waiting for a friend to bring over his skidsteer with 18" auger to dig a 4' hole on this Rocky Mountain hillside. In the meantime I'm considering painting my 71/2' Paraclipse. Looks like it was powder-coated but it's mostly worn off leaving a metallic finish. Being new at this I have no idea about best/worst colors or type of paint for best reflection (or should I not paint it at all?). The dish is aluminum I believe as it's very light. How about gray self etching primer? Or black? Anyway I think aluminum would need primer. Suggestions? Thanks.
