Hi Tsikoteer Gurus,
First of all Does anyone here knows the real difference between undercoating and rustproofing.
Second, I saw that my underchassis has some rust already formed near the rear wheel. Is there anybody here knows where I could get undercoat or rustproofing (whichever is better). Yung bang iniiscrape muna at pinalilitaw yung metal bago applyan ng coating. Ano ba talaga ang kailangan ko undercoat or rustproof.

TIA!
