Wow, you're certainly getting to know your GS!
Was it just the radiator weep that prompted you to start the job?
No, not really, its just sort of snowballed! When it had its inspection at emblem they picked up that there was a bit of play in one of the front upper wishbone ball joints, and as the front tires are badly worn on the inner edge I want to get the alignment done, but there's no point doing that with worn components, so got the joint sent from America as cheaper than over here! and when dropped the front undertray there was a very slow drip of coolant. so thought, 'oh well might as well do that', also bought the last set of forum discs and a set of **** stainless flexi brake lines, as well as a set of bellows for the steering rack as they were showing signs of perishing, and you know what its like, as your working on a certain area of the car you might as well do other things as you have already got it apart. Of course the hard brake lines broke when taking off the old flexis, so they have had to be replaced, also treated any corrosion on the subframe with 'Fertan' rust converter, followed by satin black hammerite, and then sprayed with underseal with added Waxoyl. Was going to try and do the rad without taking the bumper off, but then noticed flakes of rust on the splitter, obviously dislodged by other works, so knew what that was likely to be, so off came the bumper, and the bumper support bar had turned to dust, so I have had to make a new one of those. the front is starting to go back together now, and then on to the rear, for new brakes, handbrake cable and free up the track control arms in preparation for its allignment, allong with 3 new tyres so i will have a matching set of Goodyears. I am also 'de stickying 'the interior, and have had the center dash vent and the door handle shrouds carbon dipped. I am also trying to do a refurb on one of the front wheels which has obviously been replaced as the inner face is a different colour to the rest and badly coroded. I also sent the front anti roll bar to be powder coated as it was going a bit rusty.
