Guys hope you can help. I got my new car at the beginning of the week, and after cleaning it today and looking in the sun, I can see what I can only describe as someone has washed parts with a rough sponge or sorts.



I have a PC, but have never used it for anything other than waxing and light polishing.

I have Megs #80, PB 1.5 (I think) and some scratch X.



Any help suggestions on what to do, this makes me so sad.

hit it with some #80 on a polishing pad...firm pressure on the machine head , and do small areas at a time



its takes a little practice to get the technique right, maybe spend some time reading up on it first, theres some good how to`s on autopia`s home and on meguiarsonline



* edit just noticed you own a audi, try the #80 but you might need #83...they have hard paint :(

Thanks Steveo,



so what would the process need to be. Its really only the bonet that seems to have the bad sratching.



Wash bonet, then do I need to clay, then apply the #80, buff off and if needed repeat? Do I use the Sonus Orange pad for this? Then after the #80, should I use AIO, sealant, P21S, Megs #16.



I have never dealt with anything like this before as I have never had a car with this sort of scratching.



Also what do you think the chances or sorting this, or do I run the risk of making it worse?

I guess actually its probably best to use the softest pad I have initially, and change pads according to the results.



Fingers crossed. Might have a go tomorrow, if not wait until next weekend.

Unless the clear on your A3 is somehow different from that on all the (12+) Audis we`ve had, it`s gonna be very hard. Sorry they messed it up so badly.



Assuming it`s like the clear on my Audis, the #80 won`t be enough to correct it and no, you won`t run any real risk of making it worse.



The only way I can do correction on Audis with a PC is to use 4" pads. They`re much more aggressive than the usual 6.5" pads that are so common. But you`ll still need something more aggressive than the #80 to really get it nice.



Unfortunately the products I prefer are out of production and getting hard to find. Anyhow, they`re 3M PI-III RC (05933) and PI-III MG (05937). Many passes with the 05933 and then a follow-up with the 05937.



In the absence of the above, I`d recommend you look into the polishes from 1Z, they`re very user-friendly and IMO that`s important as you`re gonna have a big job ahead of you. Their Paint Polish might be aggressive enough, but you might even need their Extra Polish. Follow the Paint Polish with their MetallicPolishWax.



There are a lot of good choices you can use instead of the above, but I`d rather recommend stuff that I know (from first-hand experience) has worked well on Audis for me and others (including people who aren`t really into detailing).



I wouldn`t plan on using the Klasse twins or any other sealant approach. Just not likely that you`ll get that black Audi paint as good as you`d need to for a sealant to look that good so I`d stick with a carnauba approach like the #16. It lasts a long time and you`ll *love* the beading.



Sorry if the above sounds negative, but I`ve been dealing with Audi clear since the early `90s and it`s quite a challenge.



Oh, and claying is advisable but not necessarily mandatory.



One other thought: if there`s any chance the hood/bonnet was repainted that could change things drastically. If that was the case, I`d begin by having a serious discussion with the dealership.

What Accumulator said is good info...I PM him yesterday about a product from 3M..it is new..to me any ways..it is called 3M SCR...I got a sample from a body shop to try out...it is made for hard scratch resistant clear coats...and Audi paint fits that title...I went to the 3M site to find info on it ..but just a picture...I read the bottle at the shop...and it states for newer hard finished clear coats...

It gave different ways to used it....from a refinish to a new car...this product may help you..may not...as said new to me..and I have not tried it yet....cost is 29.95 a quart...



go to a Audi body shop and ask them if you could buy a little of it..if they have it...to try on your paint..they may just give you some..never know....or go to a 3M dealer and buy some...

Thanks for the responses guys.

I am not sure what to do, part of me thinks I just need to try and forget its there.



Just for clarity, could someone define the term pass. Is it as it sounds, multiple passes = pc the mark many times?



I may have a go with the #80 and see if it does anything, if it cant do any harm then I guess nothing to lose.

#80 will make things a lot better (with a few "passes", see below) and this stuff is only as important as *you* want it to be ;) Use it until you`re tired of doing it and top with wax.



A "pass" is a single application. Apply the #80, work it until it starts to get transparent/clear, buff off. That`s one pass. You`ll have to do *multiple* applications like this because your paint is hard.

Many Many thanks guys. Its hard to see for normal people, but anal people like ourselves will always see it if we want to. I will see how I go, and then maybe have a go one weekend when its not to hot.



So Humid here at the moment, soon pass though, then its back to rainy UK.
