I Have several original door protectors in front of me over time they start to pit and the chrome gets scratched with rings, key etc and just general grit, the original were plastic, the remakes were brass chromed and as said above already an agreement was made with any members whom purchased them would not gain from selling them on, some decided not to stick to this agreement
few photo below of the ones I have, note the pitting.
Fitted on the car from a distance they look great, up close not to good.
