Airstream Plastic Rock Guard Maintenance

maintenance on your airstream plastic rock guards

After a couple of thousand miles of towing, I decided to do some clean-up and maintenance of my Airstream’s plastic rock guard on the front windows. I had noticed the inner gaskets of the smoke-colored window rock guards were beginning to come out of their groove in the corners and wanted to push them back where they belonged. I also wanted to clean the windows and the rubber gaskets that surround them.

Below is a photo of the supplies I used – ordinary glass cleaner, 303 Protectant, a putty knife, and a couple of microfiber cloths.

The attachment mechanism for the smoke-colored side window rock guards has two screws on each side. You must open the center smoke-colored window guard to access these screws. These are NOT threaded screws. You only turn them a quarter turn counterclockwise to release them. Turn them both to loosen them and then pull the screw mechanism out of its attachment hole. This will cause the rock guard to drop a bit, and it’ll be hanging on its hinges. Don’t let go of it! It can swing all the way around and the back side can hit the trailer skin, causing a crease.

Below are a couple of pictures of the window guard attachment screws. I hate to call them screws because really, they’re not screws. When you go to re-install them, you have to lift up on the attachment end so you can push the little tab into the rubber grommet, then turn the screw a quarter turn to the right to secure it.

I cleaned all the debris out from behind the rock guards, cleaned the windows, and applied the 303 Protectant to all the rubber gaskets.

I used the plastic putty knife to push all the round rubber gaskets back into the corners. The first picture shows how the gaskets begin to come out at the corners. Some were out 3 or 4 inches from the corner. I cut one right at the corner and shoved it in the groove, so constant movement and tension won’t cause it to start to come out again.

I also put a little white lithium grease on the center rock guard slide mechanisms, as seen in the second picture here, greatly improving the ease of opening and closing it.

All in all, an easy job that anyone can do. Please post questions or comments below.
