Removing Etchings - Need Advice - BMW 3-Series (E90 E92) Forum

Take a Look, here's what I'm working with. Also some haze going on with these panels. Talked to a painter and he advised that this could be removed (etchings and haziness) with a 3000 grit wetsand and polish. He was very hesitant to do any paint work to correct the problem.

Try to polish it out with a DA first before sanding.

What type of equipment do you have? Polishes??? Pads????

They look like water spot etchings; no need to wet sand (most likely) and definitely no need for respray. Use compound, then polish, then final polish.

You dont need to wet sand that..not even use an agressive compound..

Light to medium duty compound and then polish should do it

I have experience using an orbital, but not a DA. How about the haze? Is this a job best left to a professional?

The haze can be polished out with a m205 and a finishing pad. That combo might even work on the water marks (with a DA). These are not an uncommon occurrence and can easily be handled by a novice with the right technique.

Thanks for the tips all. I'm going to head over to detailed image and get sorted with some products. Sounds like I can do this, rather than pay a professional, so I'll buy my own gear

I'll post pics of the process and results.

this should be very easy for you.. like the others have said. a medium compound polish maybe paired up with the LC orange pad on a DA should tackle this.

Order placed with DI

Can't wait!

I have finished the hood and fenders and the results are stunning. Pics to follow, but thanks for encouraging me to tackle this myself! Pads are now drying after being cleaned.
