So yeah...after winter I figured it would be a good idea to get under there and spray it all out-so I took some stuff called oil eater and sprayed it all up under there then hosed it all down, then repeated. Seems pretty clean, but I was thinking about getting my car re-undercoated or having some sort of rust-inhibitor applied. What should I do or where should I go to get this done? I talked to one of the guys I know at Honda and he wasn't even really sure what I should do-but mentioned spraying used motor oil over the bottom of my car. I didnt like that idea as it would attract dirt...so any others?
