I'm expecting delivery of my 2013 335xi sedan in late August and am considering applying ASAP an effective, long-lasting sealant to both protect the finish and avoid frequent waxing or detailing. I'd also like to avoid overpriced, short-lived dealer treatments!

I have heard very good things about the Opti products and they claim they are "permanent", not requiring periodic renewal applications every 6-12 months like some other products. Having no experience with applying such products, I'd probably want it done by a professional.

Do any of you have experience with the Opti products and, if so, what do you think of them. Also, can anyone recommend reliable detailers in the Washington, D.C./ No. Virginia/Maryland area who would be willing to prep the car and then apply it.....along with some idea of the likely cost involved.

Thanks for any and all ideas and suggestions!
