Waxoyl?

[DanH]

Anyone bothered doing this to an RS etc? Any downsides and any idea where I could get it done in London/Essex?

I know the TVR crowd are big on this, but thought I'd ask here first.

Yes, it gets done to a lot of UK RSs. Virtually any competent garage can do it; some have their own preferred underseal. Ask your Porsche independent to underseal the car for you. It adds a little weight and the RSs are galvanised anyway, but it is probably a good idea if you drive it over the winter months.

I asked JZM about doing it and they don't do it! Anyone have any recommendations for someone who'll do a decent job of it?

I may have to ring a TVR garage

They just don't want to get dirty, LOL.

Autofarm used to do it from memory. Or try a more mud n guts indie, like a Land Rover specialist.

Try Terry's Beetle services in Hanwell, West London

£275 for my 911CS but depends on mucky the underneath is, done a top job - uses a Wurth product

don't think it mentions it on the website below

Does anyone know what Porsche use on their modern cars as standard? I realise I haven't got it, but I'd like the same treatment normal 996s have if possible.

So far had various recommendations, including not to do it at all. Also talk of injecting waxoyl into sills etc which seems OTT?

[clubsport]

Dan, keep it standard...don't spoil things with hard underseal like the lardy 996 versions. Plus anyone looking to buy the car will assume it was spanked and repaired at some point...

For a winter waxoyl treatment, have the underside steam cleaned and then spray the liquid waxoyl on,,,,it sort of hardens ,,,well solidifies from the liquid state when it is warmed....this will be good enough to keep the salt at bay through the winter. In the spring just steam clean the now dirty waxoyl off to reveal a clean underside.

I have done the above on various classic cars over the years with no rusting problems,,,pointless to inject the sills....fine on an old MGB GT,,,but they were never galvanised like your Porsche.

Now read that doing this during winter is a bad idea as it won't dry properly so waxoyl will trap moisture? Thoughts?

Also would you recommend the thick black waxoyl or the thinner clear stuff?

thanks.

The place that did mine didnt steam clean the underneath, just air-hose'd it, hence no moisture.

Was that Wurth product black or clear/white? Think I'd prefer to use something clear or white on a white RS.

Cheers,

Dan, Waxoyl's states that it chases water off of mild steel plate in seconds,,don't really see how it will trap moisture....i always use the thinner gold colour one...it will go blackish with road grime anyhow.....just steam clean off and reapply when required...the black stuff is a lot more permanant and wouldn't look right on a white 996.

Is it just RS's that aren't hard undersealed or all the Gts?

cheers

Just the RS.

Does ragtop fancy doing some waxoyl'ing Bruce? Dunno if you are still doing maintenance since the move?

Black, but clubsport is right, I had the clear Waxoyl done 2 years sgo, went black within 6 months or so of road use.

The black Wurth product is very slightly compressible - seems to have reduced road/tyre noise a tad too
