    Haze difficulties

    Started work on a 60-day old, new paint project. Flaws were minor sanding marks. Did four test areas of Ultimate Polish, Ultimate Compound, M105 and D300. Although the D300 has zero dust (big plus), I felt M105 did the best removing the flaws.

    Three sets of passes at speeds 6, 5, and 4 with Porter-Cable and yellow Meg's pad. Followed that with three passes of M205 again at speed 6, 5, and 4 using a yellow Meg's pad. Pressure in all cases was heavy, moderate and then light, with slow arm speed.

    Used a product called Eraser between M105 and M205 to look for defects that needed additional attention.

    Followed up with D301 on a Meg's finishing MF pad at speed 4 moderate then light pressure.

    I'm not happy with the amount of hazing that remains. After this much work, not seeing the clarity I would expect.

    Suggestions?

    Re: Haze difficulties

    David, what were your findings following the Eraser wipe down after the final M205/W8207 yellow pad? Was it haze free then or no? Are you still seeing the remnants of the sanding marks? Those are two different situations that would require two different processes to correct.

    If it is indeed some DA haze you're battling then you could be facing very delicate paint. If so, we'd suggest running M205 again but this time on a black W9207 finishing pad at speed 3 to 4, moderate pressure, and a fairly short buffing cycle. Give it another wipe down and, if needed, give it another go with M205/W9207 at a slower speed and less pressure. If, in fact, you're dealing with very delicate paint then skip the microfiber finishing disc/D301 and go with a fresh W9207 foam finishing pad and test with D301, or just move to something like M26, NXT, etc.

    If you're actually chasing the remnants of sanding marks, then you might need to step up the aggression level of the first cut to remove them. Given your arsenal we'd suggest running M105 on the microfiber cutting disc with pretty heavy pressure and slow arm movements at speed 5 to 6 on your PC. Follow up with M205/W9207 or W8207 as needed or, if the finish is looking really good, just go with D301 on the microfiber finishing disc.

    Michael,

    Answering your question, after M105/yellow pad most sanding marks gone, hazing evident. After M205/yellow pad hazing still evident. I intended to use D301 to remove hazing and add wax to help protect completed area when working on the rest of the car. This process was unsatisfactory.

    Today, following your advice I taped off a 2x2 Area in a previously done area and got very aggressive with M105 and correction MF pad at 5 and 6 PC speed. Followed with M205 yellow pad moderate speed and pressure. Followed that with M205 finishing pad, PC speed 3, light pressure, fast arm. Comparing this redone area to previously done area, redone looks nearly defect free and darker black (less hazing).

    However, two problems. Clear coat is ridiculously delicate. Wiping off spent M205 results in swirls if too much pressure or less than premium MF. Also primer visible through base coat and clear coat adding to impression of hazing. Will meet with painter/owner to evaluate.

    Fearful of how to maintain this delicate paint as defect free while correcting the car.

    Thank you for your guidance.

    David, if the paint is that super delicate that even wiping off wax can create some marring, you might want to look into finishing with D301 on a foam finishing pad, and lay down as thin a coat as you can. Wipe off of D301 in easier than anything in our lineup so that should go a long toward minimizing an marring at the end.

    Re: Haze difficulties

    As often happens, things change. I met with owner/painter/seller and he indicated the potential buyer might be tending to family matters(divorce) first, causing the buyer to re-think the purchase. The project has been put into a holding pattern.

    However, I will finish off the area already started. I had been debating in my head if I could use Ultimate Polish and then hand apply M26. I do like your suggestion better. Fewer times touching the surface.

    Thanks for your interest.

    If you get a chance, please keep us posted on whether or not the D301/foam pad process helps or not.
