Hi Number001,

thanks for the explanation.
I also read from other threads na possible pa rin ang rustproofing even outside factory, but applying wax instead.
I've searched the thread and it's a little kinda old already. Chiefy is nowhere to be foound. LOL. Undercoating to gasoline stations na lang ang suggestions.
Hope somebody could suggests good undercoat services. yung litaw muna metal before spraying undercoats.
TIA.
