black paint is now brown

[andyo]

i painted my grand national last year before winter so the paint can breathe and i can wetsand and buff in the spring.

i wetsanded and buffed with 1,000 2,000 2,500 3,000 paper and disc. then with g100 and lc yellow, meg yellow, 105, 205, up, then gc carnuba wax.

i do have the DA microfiber kit and it didnt even take out the 3,000 grit sanding marks so i used the above.

the car looks crazy black in the garage, shade and when it is dark out, but in the sunlight it looks like a ups truck. here is a pic

I've seen over the counter black paint turn to a brown look in a lot of instances. It's just not the same as the pro-quality paint.

I agree. Looks like it was sanded/polished a bit too much. It appears in the pic as if the clear coat is almost gone.

The DA Microfiber System should have been much more aggressive than M105/LC Yellow pad and we would imagine it should remove those 3000 grit marks. Unless, of course, the paint is quite hard. In that case you're going to struggle to remove the sanding marks, even at 3000 grit, unless you step up to a rotary buffer. Traditionally that's the tool, along with a wool pad and a fairly potent compound (M105 is the logical choice here) to pull out sanding marks.

The paint looks, at this point, to be pretty badly hazed and it could be that we're still looking at remnants of sanding marks. It's a bit hard to tell from the image, but it sure looks like you've got some shinier areas that indicate high and low spots in the paint texture. That tells us that you've still got that hazy look that comes from only partly removing the 3000 grit marks. As you sanded progressively finer you probably noticed that you saw an increase in gloss as you moved from 1000 grit (no reflections at all) to 3000 grit (fuzzy reflections, but reflections nonetheless). Some fairly aggressive compounding is needed to fully remove those marks and bring the gloss to the level you want. And these remnants will disappear in the shade but show up better in direct light. Why it looks brown, however, is a different story and may or may not be related to the sanding mark remnants. Or it could be the paint itself - a bit difficult to say at this stage.

Let's see about getting those sanding marks fully out first, though, and then take it from there.

Do you have any experience at all with a rotary buffer?
