It sounds dubious, but they actually lift tiny imperfections/microscopic debris from the surface of the paint leaving it impressively smooth, ready for a top-coat of wax or sealant.

Before the wax or sealant, I'd polish the paint to get the best shine and remove any marks or blemishes the clay bar didn't get rid of then wax or seal.

Hi! Sorry...this is going to be a bit rambling but I hope it helps!

*Motoring bit*

Lots of good points mentioned above. A small note about parking....always park the car in the direction of travel. If you spot a space on the other side of the road you have to do a U-turn before parking there (the time spent turning around normally means you lose the spot but at least you won't get hit with a parking fine!). Traffic wardens (or Rangers as they're known here) generally patrol in pairs and won't take pink fluffy dice from anyone!

Definitely make sure she is aware of how much distance there may be in between towns, especially in the Northern Territory and Western Australia. A lot of visitors, myself included, found it very hard to comprehend the distances! 5 hours of driving with nothing as far as the eye can see can be very daunting. In these regions (esp. NT) always make sure you have lots (and I mean lots) of water and if you break down NEVER leave the car. It may be the only shelter from the sun that you have.

In the cities be very careful of taxis and buses! Driving in Sydney is sometimes not for the faint hearted! Nobody seems to use their mirrors and people generally don't like letting you in! Apparently you have to give way to buses....if you don't they'll barge their way in regardless (bit scary when it's a bendy bus!) Red lights don't generally mean stop! As a pedestrian ALWAYS check that the traffic has stopped when the little red man turns green. Many a time a bus/taxi etc has come speeding through a red light and nearly taken out a pedestrian right in front of me! If you are turning left you have to give way to the pedestrians if the little man is green!

As said earlier the police are everywhere! RBT (random breath tests) are set up all over the place and at any time of the day. They can also do random drug tests if you seem off your face! On long weekends double demerits applies....i.e. for an offence you'd normally get 3 points for, on a long weekend you'll get 6 and risk losing your licence.

During school term there are 40kmh zones where, between certain times in the morning and afternoon, you can't go over 40kmh. You'll generally know where these are thanks to the large signs and people all slamming their brakes on!

Dawn and dusk are the times when the 'roos are at their kamikazi best! Watch out for the Emus and Wombats too....both will do serious damage to your car. The number one rule over here is that you NEVER swerve for an animal. So many people have crashed and died trying to avoid killing a furry beast when, if they'd just gritted their teeth and hit it head on they may only have had to deal with the problem of some serious dents and/or the remains of a native animal sticking out of their front grill.

*Travel bit*

I've spent the last 3 years here. 1 year's worth of travelling and 2 of studying in Sydney. I've only got one last bit to see then i've pretty much done it all! This is what I'd suggest:

As she'll be arriving in July I reccomend she flies into Perth (only 5 hours from Singapore). The weather won't be particularly warm at that time of year down south but it's a perfect time to head up the west coast. Wildflowers were out, everything was green and healthy and it got warmer and warmer the further north I travelled. There's heaps to see, my favourite being the Monkey Mia where they have regular visits from wild dolphins and Ningaloo Reef near Exmouth - at Turquoise Bay you can literally walk off the beach and within a couple of metres you are surrounded by tropical reef fish and amazing coral! (It takes about an hour or so to reach the Great Barrier Reef from Cairns.) I'd recommend getting one of those waterproof digital cameras for her travels...the disposable ones are rubbish and you do tend to find yourself snorkelling a lot here!

Spend a few days in Broome before heading to Darwin. If she buys a 4x4 for her travels then the Gibbs River Road which runs from Derby to Kununurra through the Kimberley region is a must (there is a tarmac road that circumnavigates this area)! 'Winter' is the only time of year that it is manageable by the inexperienced! There will be plenty of other backpackers that will be keen to car share.

From Darwin she can either drive down through the centre, visiting Alice Springs/Uluru/Kata Tjuta etc and continuing south to Adelaide or she can drive to Cairns and head down the East Coast. I wouldn't recommend doing the 'red centre' any later than October/November. I was there in September and it was already starting to heat up quite seriously. In the height of the summer the flies and heat would be unbearable! She could always head to Alice from Darwin and then make her way over to Cairns on the East Coast (other than Coober Pedy, there isn't much between Alice and Adelaide!). Late September in Cairns was perfect. Heading down the coast as summer arrives means you arrive in Sydney around November/December in time for Christmas and New Year. Nothing quite beats watching the NY fireworks over the harbour although I don't recommend being close to the action....you lose the effect of the many pontoons of fireworks spread throughout the harbour. Heading to South Heads (near Watsons Bay) will give you an amazing view of the harbour!

After Sydney carry on South to Melbourne either via the coast road or through the Snowy Mountains. Do Canberra just to say she's been there but avoid staying too long! Probably the most boring city I've ever been to!! Tasmania is awesome and overlooked by many! You can take the ferry over from Melbourne and it's v.easy to drive around! From Melbourne head along the Great Ocean Road via the Grampians National Park to Adelaide. Visit Kangaroo Island and the wine regions before heading across the Nullabor Plain back to Perth. Don't forget to head down to the south west to see some pretty amazing trees! (not as boring as it sounds!)

A very useful travel forum can be found here: www.lonelyplanet.com/thorntree/forum.jspa?forumID=...3 and if she's planning on staying in hostels then this website is pretty helpful when looking for a decent one! www.hostelz.com

Phew!! I think i'm done!! Hope this helps!

She's going to have a ball!

my mate had a 125cc bike for 9 omnths before he stuck it in side of a car, totally there fault you understand thats why he never got any compensation or another bike....buys a car a couple of years later he's had about 7 or 8 crashes without needing to involve the insurance (friends, familes...and cash in hand).

Good for him I say.

You could try taking out the pads and cleaning the back of the pads, pins and all around. If the outer edge of the disc is rusty, give the wheel a spin and clean that too with an old screwdriver pressed on. Reassemble with a smear of copper grease ON THE BACK ONLY of the pads.
Usually stops these annoying noises.
