Underside clean up on my Boxster 987 S 08

Hi Folks, I plan on cleaning up and restoring the rear end  underside of my 987 S this summer. Although I do intend to consult with my local Porsche Centre in Glasgow first to hear what they recommend in terms of do's and dont's, but I just wondered if anyone had already attempted this and what was applied as a lasting protection. The underside on my 987 S just seems to be covered in grime with no signs of corrosion but for sure I want it cleaned up where possible
 
The other thing, I've come across a company in Sweden called Pela Tools that offer low profile car ramps, simply drive on and work the hydraulic pump where both ramps lift the wheels in a scissor type fashion giving brilliant access to get underneath with safety locking pins to put in place so the hydraulic pressure can be released to enable working safely underneath without issue. Ideal for the above mentioned job pending
 
I look forward to any feedback on the above
 
Bring on the summer please!

I've recently cleaned up my sons 15 year old Type R (using the ramps at work)
 
Cleaned up initially with a warm 1:10 mix of Bilt Hamber Surfex HD degreaser and scrubbed with a brush.
Rinse thoroughly.
Left to dry
Wire brushed any loose underseal, rusty areas.
Painted with Bilt Hamber Hydrate 80 rust convertor and protector.
2nd coat 90 degrees to the first one
Painted with Bilt Hamber Dynax UB applied with brush, a dark brown hard waxy film, goes on like treacle, dries nicely though.
Provides decent impact protection around arches etc.
Sprayed other areas with Bilt Hamber Dynax UB from spray can.

Will try and fish out some pics off the phone and post them up.

For around brake discs etc I spray Bilt Hamber Atom Mac rust inhibitor.
I think its something like 50ml in a 1000ml spray bottle, so a little goes a long way
This also stops your discs going brown when you wash the car and leave it to dry.

The car ramps are OK to a point. It still means your groveling about on your knee, laying on your back or rolling on your side and still have limited access.  For what they cost you may consider a scissor lift so you can get the car higher and get all four wheels off at the same time. A much better option all round.  Head room may be an issue but many scissor lift are Portable and can be wheeled outside. The down side is you may need running boards on low slung cars (porsche).
That said I wouldn’t be without mine .
 

I might be rough but I’m slow as well

I'm in the West Midlands, but I found a local motorcycle company who hire out their car ramp by the hour, just £7/hr for any job.
Total freedom, easy access and in a few hours you can achieve a lot!
 
Maybe try locally to you?

These type of hydraulic car ramps are available in the UK https://cjautosheywood.co.uk/product/hydraulic-car-ramps-1350kg-capacity-cr012/
 
I have a pair, and offer some points of advice: for very low cars you may need a shallow angle lead in ramp particularly if lifting the front or your car (I use a two short planks 🙂), the hydraulic valve doesn’t always lift the two sides evenly so you may need to partially release one side to even them up, as the ramp rises it also moves forwards (or backwards, I can’t remember which) so ideally you should somehow lock the wheel onto the ramp before raising and ensure the wheels on the ground can rotate to allow the car to move.

Andrew,
 
I see that they offer lead-on ramps which could be a useful addition.
 
Glen, another option would be to invest in more a expensive whole-body lift like the QuickJack portable lift:

Hi all,
I know this is a bit lo-tech, but I have used a pressure washer patio cleaner attachment turned upside down. The jets spin and do a fairly good job of removing most of the crud and winter grime. The long handle let’s me get at all the underside. 
The big, wheels off, clean in the spring is done with axle stands. I’ve never put a treatment on the underside of the car.
Regards

The photo you share is exactly what I had in mind, my issue is the slope on my back yard that means I am still researching a safe technique that will work ( basically a secure means to block the front wheels from moving obviously ). Luckily my ground slope is not to the side which would complicate things more. Looks very much like the Pela Tools model I had in mind but better cause I think what you illustrate is available from within the UK which Pela is not
 
Looks like you have brilliant clearance at the rear on this example, however my question is does the nose or underside of the front bumper bottom out on the ground, is that the limiting factor or not an issue at all?

Glen,
There were no problems with the front end scraping when that car was on the ramps - it was a 2.9 Cayman 987.2 on 19” wheels. In use the ramps are pretty stable, there is a mechanical lock just in case of hydraulic failure. I think that if you were to use lightweight ratchet straps to secure the wheels to the ramp there shouldn’t be any need to chock the other end, although better safe than sorry.
 
When I bought my ramps there was a cheaper option available similar in action to the old scissor jack method. This would enable you to raise each ramp independently. Sometimes I think that might have been the better option as trying to move two ramps around which are linked to the pump by heavy gauge rubber tubes can be quite unwieldy.

If you live within easy each of the Oxford area there is service provided by a company called "This is Your Garage" They they are based at Culham and have a number of fully equipped workshop bays that can be rented by the hour. I managed to get there once before lockdown to do some preventative maintenance on the underside and wheel arched of my Boxster. The luxury of a 4-post lift for £20 per hour is very appealing and I'll be back again when lockdown eases.
