Question: Anyone out there have a Hampton HI300 in enamel that has been in use for several years? Does the enamel finish hold up over time? I heard it can chip. On the flip side, does anyone have any comments on the durability of the Metallic/classic black finish? I have read they can dull after a period of heavy use and to keep them looking nice they have to be re-painted. Again, I am talking about the Hampton HI300 insert, so it would only be the front of the unit that would be visible. I have spent the last several days reading everything I can find and viewing completed installs (thanks for posting pics!) but there is little or no information on the finish durability. Also any additional pics of this unit installed would be appreciated.
