Steve,
No worries. This is actually my 4th opinion. A garage told me two years ago that I needed struts while getting an oil change. I changed jobs across a mountain and started going to a Lexus garage. They told me last year after an oil change and brake inspection that I needed $6K in repairs. Went to another garage for a "2nd" opinion and they said I needed rear brakes. WWWHHHAAATTTT!!! I just had a brake inspection and they didn't say I need new rear pads, but told me I needed $6K in repairs. Never went back to them again, as they now had three strikes 1) after they failed to put all lugs in wheels with new tires and rear wheel nearly fell off going over the mountain home, 2) failed to put oil plug in after oil change and oil leaked all over my garage floor!, 3) didn't do brake inspection that they said they did. Done - never went back to them again. The place I went to for the 2nd opinion... had an appointment for my annual inspection for tag renewal and the lady behind the counter didn't even know about it... couldn't pronounce my last name and greeted me with "Tammy Whatever." I said, "Tammy R would be nice if you can't pronounce it." Come to find out she was the owner (gasp!). Had the inspection, heard one of the guys state that a license plate light was out. Paid and was greeted with a car with a license plate out. WTF? Done with that place. I'm hoping that this new place will be good. As you see, I've not had the best luck with garages. Seems three garages saw dry-rotted boot on strut and said I needed new struts. That's just horrible.
I drive mainly on smooth, paved roads, too, but I'm on the occasional gravel road, so I'll try your gluing approach to keep dust or dirt out as best as I can. The car rides smooth. It's a great car! I'm hoping to get three more years out of it. {crossed fingers}
