Applying Loctite may not be a good idea, this would probably act as a lubricant and using a torque wrench would allow the screw to be turned more than the specification value which is for a metal to metal contact. When cured the release torque required may leed to the head snapping off.
I realize that some people use steel or stainless steel screws but the OEM's are some aluminum alloy and that is what my comments refer to.
For the record I would not use steel screws, as I would assume that they are aluminum for some good reason.
Aluminum screws cost more and Mercedes would not use them for no good reason.
Good RTV seals require an even thickness for the best results as it will skin over evenly and compress evenly. Blobs and thin areas are not going to give a good result. Follow the instructions for the RTV used to the letter.
