A clothes steamer works really well to soften them up and then you can peel them off by hand. Then just use some isopropyl alcohol on a soft cloth to remove any remaining glue or gunk.

 

I removed the stone guards on my 2006 Boxster S last weekend . All I did was use my fingernail to lift up the top-most edge of the film, and then slowly pulled the film away from the body. There was no residue left on the body from the film when I finished.

 

Thanks, will try and let you know how it went! Thanks!

 

Its a good idea to take a few photos before you remove them so that you have a guide when it come to positioning the replacements.

 

I removed mine after leaving the car parked out in the sun all day, lifted off with out much effort, I did not replace, I do not like how they look.

 

FWIW, my 7 yr old stone guards looked awful: marks from road & track debris & discolored. I bought replacements but never got around to putting them on. A couple of weeks ago I detailed my car using Zaino AIO and my Porter Cable buffer. Having nothing to lose I buffed the stone guards with moderate pressure, black pad, #5 speed, & AIO. They now look like new, ... i.e. barely visible on my Seal Grey car. Before replacing them, try a good mildly abrasive cleaner polish and a buffer or lots of elbow grease. You might be pleasantly surprised like I was.

I would heat them up with a hair dryer before pulling them off, they can take some paint with them if you don't. I just removed mine and went bare.

 

+1 on the hair dryer - that's what I used when I replaced mine. New guards from Suncoast are relatively inexpensive, and can dress up the look of an older car. I have also found that Meguiar's plastic polish does a pretty good job of cleaning up the majority of scuff marks, but after a few years new guards are probably warranted - a real easy cosmetic improvement!

 

So I managed to remove the stone guards, a lil bit of heat from my girl's hair dryer, a plastic scraper and tons of precaution. It broke in a million pieces because the previous owner didnt took proper care of it, so glue residue was all around. Did a couple of minutes of research on you tube and saw that it was going to be either WD-40 or goo off to remove it, went with goo off because I had some lying around, either way, it came out pretty easily and after a bit of polishing, it looks good as new! Thanks for the advice!

 

A few days ago, I too had the "pleasure" of trying to remove the stone guards.
Didn't realise that they were a PITA to remove as Eunos mentioned.

took it to a professional. 2 people took about 90 mins to remove both sides that involved a heat gun, solvents, scrapers, a buffing machine and some old fashioned elbow grease.

on the engine cooling/driver's side (passenger side for the Left hand drive folk) it was cracking even before the attempt to remove it began and that took the bulk of the removal time.
The air intake (on the other side) only took a few mins with the heat gun - not sure why the 2 sides were so different.

in the picture you can see how much progress a novice took in 20 mins.

 

I took mine off too.. before I took them off I traced the pattern and used that as a stencil, then made some using 3m clear bra material...when I go to the track or longer trip I’ll stick them on... on a freshly waxed car they peel right off.. I have reused the one set I made quite a few times... Food for thought

 

Removed and replaced them (new ones are black, looks sharp against the white body). No sweat taking the old ones off, still flexible, and being careful while pulling them - they came right off. Minimal glue mess to clean up.

Let's see if I have a photo of the new ones:

Yup.. there we are. I'm thinking of painting the louvers either white or black. I think white might look very sharp..
