helped a friend to try to restore SHINNNEEEE to his wira. now, his wira's paint surface has formed an incredible think & coarse layer of sand dust / garnet dust, because the car is always parked in relative proximity to a sand blasting facilities. and the guy almost never wash there car. only occasionally send to car wash centre for basic wash, and ofcourse, the layer of hardened dust can't be washed away. when touching the surface, can almost say it felt like touching fine grade sand paper.
Picture showing before wash state. put up some close-up view dunno if you guys can see the hardened sand layer. It is most visually apparent on all the windows surface.

Step 1: so first step, naturally, wash the car first. wash with Meg UWW. when spraying the car with water, also took some photo for water beading check. as you can see, there's totally no water beading at all. the water in fact gathered on the paint surface. the gathered water is so thick that at distance, the car looks very shiny because the water is giving off the reflection. wash wash wash.

Step 2: after washing (and before drying), started to do the claying, using UWW shampoo mix & PG wonder clay No.2. yes yes i know you guys recommend me to use a shampoo only product and not wash & wax, but, that's what i only got at this moment so, just be it. Oh man, this stage is THE MOST TIRING stage! it is sooooo muscle intensive.. the sand layer is sooo difficult to remove. Me and the car owner is rubbing the surface with the clay like mad! the window is even more difficult to clay. once the sand layer has been removed slowly, can feel the clay glide on the surface easily. but a hell lot of effort is put into removing the sand layer.. spend about 2-3 hrs just to clay the whole car, by 2 ppl. but i know i need to do this stage properly as i feel that this is the MOST important part for today. my hand and arm is like super duper sour. took a picture on window showing clayed and un-clayed comparison.

Step 3: Wash again to remove the claying residue. after rinsing, took some photo again to check water beading. still no water beading even though it's UWW.

after that, drying with chamois (synthetic). the car already looks reasonably shine! not sure its my (and the car owner's) hard effort on claying, or because the UWW just make the car looks shiny after wash! even though not much water beading.

Step 4: Polishing with Meg Ultimate Polish. i actually not really sure how to apply this. for today i just apply it on a slightly damp applicator pad, and proceed to rub the surface. i say rub because i did put down some force in this stage. not sure if i induce more swirls in the process.. but anyway, most of the light scratches i unable to remove them. the only one i successfully remove a bit is the finger nail scratches at the door handle. i really think i need a DA and Ultimate compound here.. UP maybe too light/fine to do any correctional cutting and somemore, i only got my muscle, a already soured and cramped muscle from the claying stage.. and finally when buffing, i find it quite difficult to buff off the residue. when applying, i use quite little product and just try to don't let the paint surface too dry when polishing, not sure if i doing correct.
Step 5: finally, apply LSP with Meg ULW. hand application also. applying this is much more easier than the UP. and buffing off is easier also. the result (the shine) is quite good for me

Other Steps: windows cleaned/rubbed with Waxco glass polish & cleaner after claying. then, apply with PG DuraZ rain repellant. Tyre sprayed with KIT APC, rubbed with a shoe brush of somekind, rinsed. and at the end sprayed with PG tyre shine (my next target, Endurance Gel

). i was also planned for some slight interior cleaning ie rub the dash board and door sides with KIT APC, wipe-off a few times with damp/wet cloth, and finally apply with Meg Ultimate Protectant. but this step totally skipped due to time of the day is running out and ohh my arms, my hands, ohhh, just sour..
Summary: well.. i think i got about.. 70% satisfaction out from this session? because when touch the surface after waxing, still can feel some patches of paint still got those hardened sand layer feel. its much much less than before, but, still can feel with hands. but can't really help it at the same time because it is so tiring claying the car, so some parts get overlooked a bit lorr.. and also i did not attempted to look for swirl marks lol. so this car i would say need to be clayed again in near future, need to be polished with correctional power which is greater than hand applied UP. NOTE on that night, it rained and so can see that the water is beading good!

here's the photo.
