I found the following Corrosion Free:
- Robinson Automotive in Mississauga - $180
- Corrosion Free Zone / Popular Car Wash in Etobicoke - $120
A huge difference in price for the same service.
I don't want to do Known or Rustcheck because of dripping, drilling holes and possible degrading in rubber.
If anyone knows a good Corrosion Free rustproofing place, please let me know.
