Fix surface rust before Fluid Film?

[soyeahiknow]

Hi all,

So I got a new car about 3 weeks ago. I been meaning to put some under body rust prevention on it but it took some time for me to decide on Fluid Film and get it sent to me. Also I don't have a garage and the weather has been crazy here in NJ.

I finally was able to borrow a friend's garage this weekend to spray the fluid film on. However, I peeked under the car today and saw that some of the metal bars holding the exhaust and muffler already has rust on it!

Should I deal with this rust using a rust convertor/remover first before liquid filming?

I am planing on washing the underside really good and letting it dry before applying fluid film. Thanks

i would get eastwoods rust encapasulator to spray over some surface rust

If they get hot from the exhaust, there is not much you can do other than a high heat exhaust paint.

I'd consider exhaust components expendable.

They rust because they are welded to the exhaust system and are bare metal.That you will never stop.

FluidFilm and CarWell penetrate the rust and prevent new rust. So while the surface should be somewhat clean (no mud) you do not need to take care of all the rust. The CarWell shop in NY sprays school buses all summer and you can bet they are not dealing with the rust on all of them.

They do not spray cars in the dead of winter as its too cold and unmanageable to let the cars warm up then spray them.

use some cold-galvanizing spray paint on exhaust components. Rustoleum makes one.

^^^ what Donald said. I do my rustproofing in the heat of summer. The fluid penetrates better in warm weather.

The shops do it in heated garages. The shops I used to take cars for rustproofing kept the car for a number of days. That way they could wash the underside and dry it with heat lamps before applying the rustproofing.

Sounds like they were doing the job the right way. I remember back in the day when there were rust proofing shops on Long Island. I went with a friend and watching them do his new Toyota. They'd power wash the bottom of the car, spray something along the sides of the car to keep the over spray from the rust proofing material off the vehicle, and then shoot it. The whole procedure was done all within 2-3 hours. Not good......... When I questioned the tech about it he said the product was not effected by the water. I made sure never to bring anything I owned there.
