FTMFW is the general consensus here?

Any naysayer or anyone with negative feedback on the topic?

There is a small amount of rust on the inside of the lower door sills (prone and common spot on Subarus) By doing the treatment, would I run the risk of accellerating the rust in that area? Or would it help and actually slow the process.

IT WILL slow the process. but not stop it once it has begun.

as long as you dont plan on working anywhere near the underside of the car in the future… i would suggest it. If i ever bought a new car i woudl get it at day one. but the OILY mess it makes for simple stuff like installing a trailer hitch & changeing an exaust. makes it a HUGE PITA unless you like to look like a diesel mechanic.
