Lennym1984 Posted February 19, 2021 Share Posted February 19, 2021 I know that established logic tells us that Boxsters and Caymans never rust but the reality is that they do and will. Spot welds are a good example of a vulnerable area as the galvanizing will have been removed/burnt off during manufacturing processes. Now that I have got that out of the way... Given that my car is currently in pretty good nick, I was thinking about trying to keep it that way by cavity waxing the sills and rear quarters. I can access these through the plugs in the sill (a few of mine had dry rotted so whilst replacing I had a little look) and/or the side vents. I routinely wax the front arches/strut towers but I'm wondering whether waxing the sills makes sense. At present it's all pretty tidy up there so they have obviously survived the last 14 years unscathed. What's the general consensus? Leave them be or wax them up? My Cayman doesn't owe me much but given that prevention is cheap whereas cure is expensive, it kind of feels like a job worth considering. Link to comment Share on other sites More sharing options...
