Congratulations on the Mercedes ! A very nice car !
I have had Ventureshield on my '09 Grand Cherokee since I bought it new in '09.
It is a great product and has saved numerous rock chips in the entire front end and part way up the hood and front fenders of my Jeep.
You can polish it carefully like the paint, just do not use anything aggressive on it. You have to be careful, it is a vinyl material and therefore will not displace heat fast like a metal panel will.
As far as the edges - the clear bra is very thin, so there is less gunk that can get into the edge.
You just have to be very careful and make all wiping motions - away - from the edges as much as possible, so you are not moving stuff into the edges. If you do end up getting something into the edge, a small, thin, brush with medium to softer bristles can be used along the edge to move things out. Be careful here, you don't want to further embed stuff and/or lift up the edge of the Bra breaking the seal.
Sometimes, a bead of 3/8" - 1/4" 3M fineline adhesive painters tape will help keep the edge clean, just mind how you apply it and just try to get the edge covered, so you can polish carefully along that line.
You can apply a wax, sealant, coating, etc., to the Clearbra with no problems as well.
Good luck !
