    First of all I am far from a pro at this and I would recommend having a Paint Depth Gauge before attempting this

    So heres the orange peel I had on my front arches

    First I took paint depth measurements, then started off with 1200 grit then 2000 grit and finishing off with 3000 grit

    Once I was happy most of the peel was gone I polished it back up with my DA

    Once I was happy the gloss had all been restored I sealed the paint and whacked some water on it for an arty shot

    Obviously far from perfect as it was my first go ever but I am more than pleased with it, makes such a difference just looking at the car

    Thanks, I tried quite a few but I think i ended up with Meguiars 105 on a wool pad and then some Menzerna PO85RE to refine

    Threw in some 3M Fast-Cut Plus at some point too

    Would of been a whole lot easier with a Rotary but I've not stepped up to the big leagues yet

    Thanks guys, was a bit of a squeaky bum exercise but now I've done it it wasnt all that bad

    Very time consuming but I was taking paint measurements and wiping it down every 2 seconds to make sure I didnt go too far

    Great results, just bought some 2500 grade sand paper for our s4 as well. Where did you paint depth gauge from?

    Where did I get it from or where did I measure?

    If you're using 2500 grit I hope you have a Rotary because it took a long time getting the gloss back from 3000 grit with my DA, could have just been me though

    Nice work mate. Had that wing been resprayed? Normally only see orange peel like that on bmw's! Cracking results though.

    That's why I asked what polish you'd used. I always assumed it would be impossible to get sanding marks out with a DA on Audi paint. :) Very nice work. I wouldn't have the bottle for it!

    Just go for it mate, results speak for themselves, just go careful near the lines and edges, use lots of water and clay lube (I also added some ONR)

    Worst comes to worst and you cant get the marks out, someone will be able to, for a few bob

    no iy is no impossible with a DA as long as you work up to 2500 or 3000 wet sand you will be ok, I use a varaity of Menzerna cut and various polishes and top it of with Zano z3

    I'll be using my rotary with 3m fast cut and then go onto using their finer compounds. Any recommendations on measuring the thickness of paint?

    Does a paint guage not just tell you the thickness down to metal ??? whats to stop you cutting into the base coat or worse still the primer ??? or can they measure individual paint coats ??

    You are right, the ones like mine only measure to the metal but you can get ones that measure each coat and they are MEGA money

    The sort of rule of thumb is that you measure the exterior paint surface then take a measurement from inside the door shut or engine bay and subtract it, therefore you have a rough guide of how much clearcoat that you can remove safely as doorshuts receive less clear coat than the exterior

    Obviously this is not a sure fire method especially with resprayed panels, just a rough limit than you can try to stay above

    I guess if it's only orange peel your doing then as long as you don't go much lower than the lowest points of the peel effect then you should be fine... if that makes sense lol

    The other thing to point out is if the panels have been resprayed the thickness is more than OE paint so you do have more to play with.....do you have any closer pictures like the original ones to show that the sanding marks are gone? Glossing up the paint and fully removing the sanding marks are two different things tbh.

    Just concerned others jumping at this and thinking its easy
