This is a black E39 M5 that I restored in a full day. However, I decided to work the trunk last because it had water marks and Bird Poo stains burned in. (At this point in the job I was completely exhausted but wanted to get it on camera as Ive had a bunch of questions about how to remove this type of damage from viewers.) Also, Im trying to prove a point that a microfiber cutting pad can remove 2500 grit.which is CRAZY! Normally, I would wet-sand the panel to 3000, 4000, and even 5000 before attempting to remove with a microfiber pad. At this point, Im testing the cutting power of the pad to learn how strong this particular pad was. (Normally, a wool pad would be used for ease and speed in this case) Remember there are 3 levels of water stains. This was level 3 or the worst stage. Level 1 is when you leave the car outside in a quick sun shower (or sprinkler) and it can be wiped off with spray wax. Level 2 is when you need to use spray wax and a clay bar to remove the contaminants. Level 3 is when you have to level the paint (wet sand or compound) to remove the stain. Hope this helps! -L AMMO Paint Regimen: \rbrAMMO Interior Regimen: \rbrAMMO Wheel Regimen: \rbrFor more how to car care videos & full product line: \rbr\rbrCar Washing Videos: \rbrPaint Polishing Videos: \rbrDrive Clean Videos: \rbrLarrys Porsche Build Videos: \rbrInterior Detailing Videos: \rbrScratch Repair Tips Videos: \rbrAutoBlog Detailing Series: \rbr\rbrSubscribe to AMMO NYC for clean cars: \rbrFacebook: \rbrInstagram: \rbrFor more product info: \rbrAMMO NYC Channel Home Page: \rbrIf this video was helpful, please give us a THUMBS UP! \rbr\rbrDisclaimer:\rbrDue to fors beyond the control of AMMO NYC, Larry Kosilla, and Make Rain Productions, we cannot guarantee against improper use or unauthorized modifications of this information.
