so my dad purchased a Black GTI to replace our old 2000 Mitsubishi Montero back in HK so I see this: http://www.vw.com.hk/publish/vwasia/hong_kong/en/after_sales/pdf/A4_Tentcard_R17_FA_7.pdf on their site and i be like whats this wax
ah hrm guess its something Hong Kong VW Dealerships decided to bring in/make up. I can't detail it myself so gotta work something out for him
Europe and Asia have different makers for VW Care, I got some VW Germany car care prodcuts while back and they where decent (in similar bottles)...I do not know but willing to bet some are made by wurth as they use them for many products. As for the wax/sealant in questions, I have no idea.
im pretty sure that the US versions are Eagle one products...but I am not sure about other countries.
