Hi all! First time poster. I just purchased my FFH recently and have been addicted to this forum ever since. You all are a wealth of knowledge! I went to Home Depot today, to purchase foam for my grille, and found a black foam pipe insulation with a more rubbery feel. I think the black would look even better than the grey. Has anyone tried this? Does it hold up any better or worse? also, would you need a larger diameter (it seems a little less dense)? Thanks for your help!
