Hi Guys,
Did this job a few years back and thought other DIY'ers might be interested - especially as some of our cars are now 8 or 9 years old.
If you've noticed your door, sunroof or boot seals looking a bit dry (or sounding squeaky), then this is an easy way to restore them and potentially avoid the cost of replacement down the line.
There are various rubber treatments out there but today I'm going to focus on the 'official' one (probably re-packaged) that's available through Porsche - Part No: 000 043 305 61.
Admittedly, it's not cheap at c£30 from memory but it's very good and as you use so little, one 30ml bottle has seen me through two complete treatments of my sunroof, door & boot seals and there's still some left.
Tools
For this job you'll need: 'Special Lubricant', PVC gloves, kitchen roll, a couple of microfibre cloths, some glass cleaner/quick detailer and possibly a weak IPA/water mix (see below).
Difficulty
This is a very easy DIY job and requires no mechanical skills, or specialist knowledge. It just takes a bit of care & patience, plus the time to clean up afterwards.
1: First make sure the seals are clean, dry and free of any contaminants (like oil/grease) - if not you can wipe them over with a microfibre and a weak (10:1) mix of IPA/distilled water but let them dry thoroughly before applying the lube, as you want it to soak in.
2: If your car has a sunroof, then mask off the glass and protect the surrounding paintwork, as the lubricant is hard to clean off afterwards without smearing.
3: Apply a small amount of lubricant to your forefinger - use SPARINGLY, as a little goes a long way!
4: Apply to the seal and begin to spread evenly over the entire surface - being careful not to get it onto surrounding materials.
5: Pinch the seal between your thumb and forefinger to ensure maximum coverage onto the seal lip and spread each drop of lubricant as far as you can (judging your progress by the change in appearance), until the whole seal is coated.
6: Allow the lube time to soak in - I left mine for approx 30 mins and moved onto the other areas.
7: Once it's sat for a while, remove any excess with a piece of kitchen roll - being careful not to wipe it onto glass, carpet or other trim.
8: Give each seal a gentle wipe over with a microfibre, turning the cloth regularly to expose a clean area.
9: Remove any masking and clean any lubricant off the glass/panels or trim with a suitable glass cleaner/quick detailer etc and admire your work.
The lubricant rejuvenates the rubber, prevents squeaks and improves its appearance.
Hope that helps
