I took a different approach…. I have the entire rear quarter, lower sill and roof rail covered in a single piece of PPF I never liked the lines of the stone guard

On my list of things to do and not excited after seeing this thread…

I had the same experience removing 15-year old cracked and yellowed stone guard from my 997.1. Came off in tiny pieces, leaving a lot of adhesive behind that had to be scrubbed and scrubbed with various goo removers to get it entirely off. 3 hours per guard!

I'm sure it's because of the age and condition I let it get to. Heat gun only helped a little. On the other hand, putting the new guards on (cut from 3M material) took about 10 minutes!

If the stone guard has dried up and become brittle, no amount of steam or heat can help you anymore. It would be ideal if you can replace the stone guards every 5 years as it would be a lot easier.

This makes me scared to remove my full front PPF that is yellowing, they are not cracked but are definitely yellow!

Pete, I put the magnetic replacements on my 997.1 and never have to go thru that crap of removal again. I went thru h*ll removing the old stuff!

It was either $100 for both or each. I didnt really note it. Either way it was woth it.

I had stone guards on my older 993 (I decided not to have any on my 997) that dated many years back. Nothing worked to remove them until I an Adhesive Eraser Wheel (installed on a drill). The adhesive to be removed must be on metal surfaced which is the case for the stone guards (if will burn plastic). But with patience in a couple of hours, I managed to get rid of my 20yrs old stone guard. There are a few good YouTube videos (one specifically on a 993, but same process for a 997).

Has anyone pulled off the paint under the stone guards when removing them?

The "guards" My silver 2009 (bought new and always garaged) started to yellow about five years ago. I asked the dealer if they would replace them and they declined, citing possible paint damage.

After reading these posts, I will look for a detailer to do the job. Does anyone have a recommendation for a detailer in the Palo Alto, CA area that would be skilled at replacing the guards?

Thanks.

Yes, they have, but not usually the paint, but the clearcoat.

this is very unlikely to occur if factory paint.

T Silnner

Thanks. Yes, all the car is factory paint.

There are more Porsches in Palo Alto than in all of many small countries, so our site should have some good recommendations for an excellent detailer.

Actually it's not - be careful.

After reading several of these posts, I was very nervous about replacing my stone guards. However, I have to report that taking my time and using hot water from a water boiler made the work an absolute breeze. Mine were original, yellowed and pretty scuffing up from doing their job. Very little adhesive was left on the car, and that came off pretty quickly with some automotive goo gone. Quick polish with my DA and new guards went on super fast!

I don’t doubt that you can cause some serious damage to the pain, but boiling water worked wonders.

Good tip on using the wood blocks so you're grabbing more of the material at once.

I'm about to tackle mine this weekend using a steamer and have seen good results with the stretching method.
