dunks Posted February 7, 2021 Report Share Posted February 7, 2021 I've a little surface rust on the inner rear wheel arch , but looking at this picture of another car on ebay, it looks like it has a liner that covers the inner edge, but I cant see any reference to it on Porsche Parts Catalogue. Anyone know if it was an option as it would cover the rust completely Link to comment Share on other sites More sharing options...
edc Posted February 7, 2021 Report Share Posted February 7, 2021 There is a wheel arch liner but the edge is uncovered. The edge has a fold or trough enough to trap plenty of mud. Lots of cars seem to have wing it arches made this way. Link to comment Share on other sites More sharing options...

Where nobody will see it), just clean it up and paint it with epoxy mastic (don't bother with POR15, it's expensive and a faff) and then, if you want, you can cover in stonechip Link to comment Share on other sites More sharing options...
Crazymind Posted February 7, 2021 Report Share Posted February 7, 2021 If it is just surface rust, sand it, use rust converter and paint it. Clear coat to make it look nice. Link to comment Share on other sites More sharing options...
½cwt Posted February 7, 2021 Report Share Posted February 7, 2021 The arch liner sits inside the metalwork return on the arch. From that view it has reminded me they can also rust driver's side where the deadening material is applied inside just below and to the rear of the engine bay vent opening.

This happened to mine on the passenger side vent The garage ended up having to cut a large piece of metal out where it had rusted from the inside, no point In Trying to fill the area with filler, it needs to be cut out to stop it returning i did a thread on it somewhere if you do a search.

Crazymind Posted February 8, 2021 Report Share Posted February 8, 2021 Bit extreme if it’s just surface rust. Link to comment Share on other sites More sharing options...

The rust around he vent is not surface rust, it rusted from the inside out so looks like surface rust, see my other thread, the foam backing that is glued to the inside panel under the vent traps water and causes major rust issues Link to comment Share on other sites More sharing options...

I took it to a local body shop who have done a few Boxsters repairs and resprays over the years and he advised popping out the vent moulding, strip off the foam on the inside and if the metal is not coming off in flakes of rust make sure it is dry and paste it with grease to stop it deteriorating to buy a couple or even a few years to consider what to do with it.

I did this on both sides with a liberal coating of wax oil to prevent further rust hopefully Link to comment Share on other sites More sharing options...
