I have some experience to share, and something to recommend based on my experience. I purchased Rim Savers from rpmtesla.com (no affiliation). I had them installed by the company that did PPF and ceramic for me - They did a great job, and said they'd only charge me an hourly shop rate. The things looked great IMO, worked perfectly for many months, didn't come off at all... Until, blammo - I hit a curb pretty hard, and part of it came off of the tire I curbed.
I looked around for some replacement edging, and found a cheap one on Amazon - The Rim Savers were kinda pricey ($80 for a set, I believe), and I just needed it for one tire. Big mistake. First of all, it didn't perfectly match color & shape. But more importantly, even though I had the same guy install it, it started coming off by the time I got home.
So I "suffered" with having one rim saver off for a few weeks, but when a friend was over I told her (yes, a female) about my plight, she said, "well let's go do this." So she and I took leftovers from the originals such that we could piece together enough for one whole tire. So we got all the original materials, including the cleaning agents, pieced it together and installed it. It looks great, and hasn't come off, even a little bit!
Here are some tips if you do it yourself:
- Cleaning the rims is easily the most important part. Do it thoroughly, just as they describe using the materials they provide / describe. You have to get every bit of grime and what-not off of there. Can't stress this enough.
- We wore gloves when handling this stuff and was careful not to touch any adhesive.
- They give you this little piece where you cover the "joint" as you roll the thing up. We think it looks better if you cut it a little long, then carefully cut and super tightly stuff the thing in there. If you do it well, you have to look pretty close to even tell that there's a joint there at all.
- When you cut it, try to make it as clean a cut as possible such that it is fully flush with the other end you're "connecting" it to. I think a sharp razor works best. We first tried regular scissors and the edges were a tad uneven, which made it difficult to smush together at a joint (the goal was to make it look as seamless as possible).
Anyway, some people hate the look. If you do, you can still use the rim protectors, just get black or some color that you can't really tell is there. Personally, I like the look and the functionality, and as long as you do it right I definitely recommend it.
