I tried this with mine months ago. Actually, Mazda of Canada suggested it to my dealer. I don' t know if they just did it wrong, used the wrong plastic or what, but it was REALLY bad afterwards once it started clunking again. It would actually creak as I sat in the car. We took it off. It'll scratch of the bar as well if done wrong. We tried the plastic trick 3 times...nothing.
Funny this should come up. My dealership called me some time ago, and said the head Canadian district reps and managers are coming in to check on the dealership on the 14th....they do this from time to time with everyone. Anyhow, he wanted my car there so he could show them. So, I left her there all day, and the manager of my dealership took them all out in her, and they all heard the noise. Of course, the squeaky shocks never made a noise ( it was raining, they don't ever seem to make noise when wet ) but the clunk apparantly....clunked quite bad. They were not impressed with it. For now, they are going to get me yet another sway bar, powder coat the ends where the bushings actually latch onto the bar ( this is to make it thicker so the bushings fit tighter), and of course I'm getting new links, new bushings, and new strut mounts AGAIN. Appararantly, they admitted that there has been quite a few problems with the strut mounts on ALL protege's. interesting.
Also found something else out. Mazda of Canada expects the dealers to pay for all of this. Well, not this time for myself, but up to this point, my dealer has been paying for over %50 of the cost of re-doing my bushings. I had to ask, as they have been fantastic about trying to help me, and I don't think it's their responsibility to pay for this stuff.
Anyhow, this whole process is going to take weeks, and with xmas coming, I'm sure shipping will be f'd up. The MSP will probably be here by then. I'll update again later on.
Good luck guys.
