I am just wondering if anyone has used this on their seats. I have a problem keeping the parchment leather clean. If I use this spray, it is suppose to make the dirt come off easier just like Scotchguard Fabric Protector. The question is, does anyone have any experience using this stuff and how would I be able to apply leather conditioner to the seats from time to time once I spray on this Scotchguard since I would imagine it would prevent even the conditioner from soaking into the leather?
