For years I have been trying to find the best way to clean and protect the undercarriage. Mostly the suspension components, boots, and subframes. Cleaning is usually pretty straight forward, using a brush/rags and some APC. What I'm really interested in, is finding a good protectant that can be used on every surface underneath.

I have used Adam's Invisible Undercarriage before, but it's extremely messy and doesn't seem to last too long. It's also sticky and seems to attract dust and road grime. I have tossed the idea around of using some type of spray wax, but I'm afraid this method wouldn't be good for any rubber parts like boots and bushings.

Any input on your undercarriage methods would be great!

 

check out Bare Bones Undercarriage Spray.... spray on, leave for 5 minutes, then wipe down and it'll leave it shining clean. My understanding is it's safe to use on all pieces...

 

as much as it sucks, I think the only "real" protection you can do for your undercarriage is to clean and condition accordingly. I have "heard" spraying wd40 on everything leaves a protectant layer, but I dont think Im trying that.

 

I'm not sure if this is right, but I take an old toothbrush and water with some dishwashing liquid in it to clean off all the rubber boots. Then, I dry them off and spray 303 directly onto them for protection. The last time I've done this was October, and the boots still seem clean and good to me since I put on your coilovers.

 

I use Griot's Undercarriage spray. Its a little messy and I lay some drop clothes down, but its really only messy if you over use the stuff. My suspension, and fender liners stay nice and black and new looking and I dont feel that it attracts dirt. My fender liners stay nice and black for a long time.

 

Thanks very much for the feedback guys!

I have thought about using 303 on the rubber parts. Seems to make sense. If it's meant for protecting trim, tops, etc., figured it should do just as good under the car.

 

Pete- bare bones from chemical guys is awesome
