The window rubbers will be replaced during each restoration. In most cases, they are weathered, resulting in leaks. Good quality rubber is an important aspect, lower quality can lead to leaks and premature dewatering of rubbers.
Standard rubbers did not have a moulding groove, these rubbers were often used by Volkswagen on cheaper VW models and on all VW Thing models and VW Split Buses. For the VW Beetle, in addition to the complete sets, the rubbers are also available separately for all other models.
Most of the windscreen rubbers are reproduced especially for Paruzzi from the original VW moulds with preformed corners, as was also the case in the original version. The cause of the leakage is in most cases the poor connection of the rubber to the bodywork, with preformed corners the rubber fits perfectly to the bodywork so that a leakage is not possible.
The easiest way to assemble rubbers is to use a piece of rope, and you do it as follows:
1. Tighten the rubber around the glass
2. Place a piece of rope in the groove, which then falls into the bodywork
3. Lubricate the window rebate with glycerin (see also the note)
4. Press the window with the rubber and the rope against the rebate
5. Pull the rope slowly inside so that the rubber falls on the vertical edge of the body
6. Once mounted, push the window into the rubber and check inside that the rubber is in the groove everywhere
Only two people can fit the rubbers, one of you press the window into the groove and the other one slowly pulls the string from between the rubbers from the inside. At the point where the rope meets, put them a little bit on top of each other, this will make it easier to retract the window afterwards.
Note : Use only glycerine and no other lubricants such as grease, soapsuds or other agents when assembling, these can corrode the rubber and result in dry cracks within a year. If it cannot be proved that glycerine has been used during assembly, the guarantee is excluded. Please order the extra glycerine as listed on the options tab.
