A.salam, I wanna know if I should use rubberised undercoating on in the inside of the rims of a cg125 to protect it from rust or should I just spray paint it. And should I use the undercoating on the inside of the rear mudguard? It’s a 2023 model, clean bike, the inside of the rims are slightly rusty, since I wash it a lot, but I’m gonna ruin the rust before I spray paint them or apply the undercoating.
(What should I use: Rubberised Undercoating, or spray paint.)
