If you're OCD about car cleaning - then strip it off and add some decent protection.
Simply put, Diamondbrite is a synthetic sealant, and while as a sealant it works ok, the whole system is fundamentally flawed.
No sealant is going to last long term (say more than 3-6 months) before some quite serious hole start appearing in your protection. Now as an example, it takes me over an hour to create a good sealant layer on thoroughly prepared paintwork - do you really think Diamondbrite can do that simply with a top up from their 'conserver' on less than perfect paint? I would suggest not.
Much better would be to strip back the diamondbrite sealant (the entire kit sells for a fiver on eBay by the way, I really hope you didn't pay to have it applied, it's the biggest dealer rip off on the planet in my book) and look to apply a good quality sealant yourself such as FK1000P or Autoglym Extra Gloss Protection. Alternatively, you could wax the car, which is a whole lot more satisfying (or maybe I'm just sad) than using the diamondbrite stuff anyway.
