Audi A4 B8.5 swirl marks.

Truckermal

Hi I have a 151 A4 and after compounding and polishing it still has swirl marks everywhere, they are like hairline scratches and I Never wash with a brush..

Any products I can use and I have a DA!

I used AG super resin first then when that made no difference I used Merenza compound nice and light which bought up the colour very well but loads of swirls left..

German paints are known to be hard. For this reason, you need to try different combinations of polish and pads to get the desired results.

Start with the least aggressive combination of polish and pad you have and work up until you get the desired results. This will ensure that you don't unnecessarily use an aggressive combination and end up removing more paint than required.

I have the following polishes (you may have other brands);
Menzerna Final Finish 3800
Menzerna Power Finish 2200
Menzerna Heavy Cut Compound 400 (Heavy Cut)

Pads ranging from finishing to heavy cut.

What worked well for me on my Golf (similar paint hardness) was Menzerna 2200 and a black finishing pad. The final pass over the car consisted of the same pad with Menzerna 3800. This removed 95 percent of the swirls which was enough for me at the time.

I know the above isn't a definitive answer to your question. Curran, FN, Vectra, MM etc., may be able to point you in a more direct manner but the above is the process on how I polish my cars.

Cheers Ron I found Autosmart compound in the shed and used that! It worked a treat my hands are falling off me though....

Ron's post is all you'll need apart from one one - time. The longer you spend on each panel the better job you'll have.

Removing swirls is 20% the correct pads/polish and 80% patience.

The next person who says detailers have a handy job gets run over by a Scania!:o

Dont know how I missed this post originally.

SRP wont have done anything other than a slight bit of colour restoration - its a polish, but its designed for hand polish as it contains mostly fillers to help hide defects.

As mentioned, German paintwork tends to be very hard; less easy to swirl the paintwork through washing, but very difficult to correct. With a DA correction will be relatively slow, but you should see noticeable results on the first attempt; jumping in with the least aggressive combo, while the right approach will result in very little head way on a DA, so on hard paints, its OK to go in with a medium pad and polish combo, do a test area and asses if you got the results you require or need to move up in the cutting ability - often you'll find that even with a heavy foam pad and polish combo, you'll still find it lacking somewhat - there are other options like Microfiber and Wool, but if having limited experience with a DA, it might be best stick to foam pads.

As Metz pointed out, with patience, correction is achieveable, it just might need two or three attempts of a certain pad and polish combo to get correction, and then another set with a finishing pad and polish. And remember, 100% correction is rarely achievable on a daily driver; and the more you remove when polishing, the less there is for further corrections. Getting 80% correction will give very good results when you stand back, and would only take about 40% of the work that trying to get 100% correction would take.

Update on this I started it 2 weeks ago panel by panel and almost finished but the results are so impressive!

This stuff is really fantastic and was recomended by D&D Detailing and really made the job easy..







The car looks way better now even from factory as it came brand new covered in swirls and marks. I sealed it with Jetseal but may get a ceramic coating soon!

Next up is my Lexus then the Scania!
