Good afternoon everyone!
My question is...I was wondering if any of you take your car in for rust protect spray? We have a few places around here...CROWN RUST CONTROL which I have used before with my other cars...but thought I would ask here first before doing anything.
Thank you

 

If this were a new car I would say yes. If this car is garage kept car and only driven in good weather I would say no. Wash the undercarriage! My personal opinion, undercoating a used car is not worth the money. I undercoated and sealed inside fenders, wheel wells and doors on one of my new cars and it was not fun. I have always felt once the area has been contaminated with road grime (used car) you will never get it as clean as you need it and that sealing over the top of it and the existing rust was a waste of good money. They say it displaces the oxygen to prevent rusting. What if it does not adhere properly and chips or opens? A great place for rust!
