DeanB Posted August 8, 2017 Share Posted August 8, 2017 So I am thinking of maybe having a go at refreshing the suspension on the old girl.  The wishbones are a bit scabby now and she bangs and clangs horribly - it really takes the pleasure out of driving the thing.  I am enjoying reading Martin and Phil's threads but my questions are these - those guys that have done this before, how long has it lasted before the rust creeps back in, what do you think is the best thing to use on the wishbones (zinc passivate? zinc passivate and paint on top?  POR 15 or some other paint?  powder coat?  something else?) and is there anything else you would do differently with the benefit of hindsight and experience? Thanks in advance for the help guys  😊  Dean Link to comment Share on other sites More sharing options...
Phil S1 Posted August 8, 2017 Share Posted August 8, 2017 From my own experience I think all I would now do differently would be using a clear coat POR15 over the passivate instead of black to keep a more OE look. The POR15 stood up really well on mine, no rust reappeared on any of the wishbones so I would readily use it again. Link to comment Share on other sites More sharing options...
DeanB Posted August 8, 2017 Author Share Posted August 8, 2017 That's good to know Phil thanks. How long ago did you do it? Â Was it about 6 years before you sold it? Link to comment Share on other sites More sharing options...
russelld Posted August 9, 2017 Share Posted August 9, 2017 I just painted mine with Por 15 ( no zinc coating as there was only rust in certain areas and I took this back to bare metal ) Still good after 2 1/2 years and my car has been outside since August 2016. I also fitted  spherical rose joints from Elise parts which contrary to what you read have not made the ride any firmer or crashier ( if that's a word ? ) Link to comment Share on other sites More sharing options...

Dr H Posted August 9, 2017 Share Posted August 9, 2017 Dean, if you need to borrow a wishbone bush tool and a ball joint tool let me know. I have both somewhere in the garage sitting doing nothing. I also have spherical bearing bushes, as Russ says no ill effects. Link to comment Share on other sites More sharing options...
DeanB Posted August 10, 2017 Author Share Posted August 10, 2017 Thanks chaps. Leigh I will probably be in touch about the tools. Â Link to comment Share on other sites More sharing options...
MattyB Posted August 12, 2017 Share Posted August 12, 2017 Just to weigh in, I was concerned about spherical bearings too - rumours of harshness, etc - however I've no regrets either. FWIW, have a chat with Dan@HPE - I was going to do it myself, but by the time I bought/borrowed tools, for what he charged I (personally) didn't think it was worth me DIY'ing it. Also, bear in mind budget creep, regardless of whether you DIY or not; there's alot more "while you're there" or "no point putting the old ones back", which for me included, but wasn't limited to: - Wheel bearings - Braided brake hoses - Toe links (I went with Spitfire) I also wish I'd have painted my calipers (or should I say, asked Dan to) because it makes the lovely, colourful and clean wheel arches look untidy Link to comment Share on other sites More sharing options...
Digimap2k Posted August 12, 2017 Share Posted August 12, 2017 About to do mine too and opting for POR15, there's quite a good Leno's garage video with the POR15 guys linked on Frost Restorations site. Sounds like you need to do a decent blast back to metal then use the right prep products for a durable finish. Hadn't realised it wasn't UV hard but I guess under the wheel arches that's no biggie.
