Do I need rustproofing?

[milkpumba]

Got a new car. Will definitely get a clear bra installed and have it undercoated. Undecided if I should get it rustproofed as well however. What are your guys opinions on rustproofing?

Vehicle brand?

Typically, water gets behind the rubber and slowly eats away with no way to dry out.
Save your money for the car wash and clean the wheel wells and undercarriage out better.

don't buy things from the dealer. dealer add ons are scams 101% of the time.

Krown or other oil/lanolin based sprays are good. Rubber or asphalt based ones are bad.
