I bought in alternative to the blue "Rolls-Royce-paste" the sealing paste on silicone-based and can this Petec really warmly recommend. Working with this paste is just a great thing. No dirty fingers, no rumgeschmierten residues or deliquescent paste and especially wonderful to dose. However, one should Petec times to inform you that at least one drawing to correct - I'll call it - reflect commitment of the tube on the back of fairly lush packaging, for I have determined puzzled for 5 minutes, as the supplied parts are used or where purpose they ever serve. When you have finally grasped how to do it, you are well compensated for the lack of sketch thanks to the wonderful handling. To paste itself is to say that they - quote at least so far - holds (proof), what it promises. Apparently it is even capable of replacing a thin paper seal. If the parts to be sealed are flat, there is no problem anyway. If the paste would be a little thinner, it would be in my opinion a little more productive.
