Hi Guys

Could someone advise what type of sealant to use on the rear quarter windows?

I assume it's not windscreen bonding seal as the rubber seal looks like it should be providing (largely) a water tights seal

I am presuming some form of panel / window sealant is used - this is generally non setting and easier to remove than windscreen bonding?

Also is there a special tool used to help insert the plastic trim that fits into the rubber seal?

Thanks

My understanding is that there is no sealant used. The rubber gasket provides the required seal.

In theory no sealent but allways best to use a good mastic winscreen sealer like 3M.

Both the rear quarters I have worked with had sealant on them, they were an S4 and GTS so I just presumed that a sealant was standard.

I think I will go with the sealant (non setting type) as opposed to the bonding type.

I have always seen butyl used in conjunction with the rubber on all 928s with exception of the very early cars.
