I am a parts adviser for Volvo and Mercedes and I just was in a class concerning the new Mercedes matte finish paint. You CAN NOT polish or wax this paint or the car HAS to have another coat of clear applied.
Doesnt remove any defects. Lightly cleans and protects, it does work beautifully though I just finished a car with it and it does make a difference.
You CAN'T! If there's a blemish on a panel or a panel does get polished or waxed it MUST be RE-SPRAYED with clear-coat. There is NO correcting this paint! You can't touch up a panel either, no blending at a bodyshop either, the ENTIRE panel HAS to have clear re-applied. DO NOT attempt top polish or wax this paint or you will be taking it to a certified Mercedes center for refinishing.
Matte or Satin Finish Paint and Body Wraps - http://www.autopia.org/forum/guide-detailing/136409-matte-satin-finish-paint-body-wraps.html]
I work at a Mercedes and I'm glad I haven't come across this paint yet lol I doubt the other two detailers have even heard of Swissvax, let alone a knowing a matte finish wax even exists... It's basically impossible to keep an entire car scratch free for very long at all, so why have a car you have to repaint every time you drive it?? Stupid.
Mercedes Magno Matte Paint is the same color coat as any gloss finished paint, the MATTE finish is caused by the clear coat. If you work at a Mercedes dealership you should be certified by Mercedes and you would have been involved in the SPMT408 instruction course called "MAGNO MATTE PAINT: WHAT YOU NEED TO KNOW (SPMT408)".
I don't know what this link goes to because I will never to to Autopia since the last time I was there I got a virus that wiped my system. The Mercedes matte finish isn't a wrap, the matte is the clear coat
The Swissvax Opaque system like a few others have mentioned IS designed for Matte Clear Coats. It was originally developed for Lamborghini when they introduced their Matte colours, this opaque system can be used on Mercedes, BMW, Harley Davidson and any other matte paint finish or matte vinyl.
I'm not certified in anything lol this dealership's priority on detailing equipment/products/training is pretty low unfortunately. I'll have to ask my service manager about it though, the more I know about the paint I'm working on, the better IMO. But to them it costs money, and they don't like that lol
As stated OptiCoat does not and should not be relied upon to fill or conceal or cover defects. ..as such you probably could not just opticoat a blemish on matte clear.
