Rickrack and I did a black Range Rover today that was a pain to polish out. Everything we put on it dusted crazy and was gumming up fast and easy. We tried a lot of different products before we came up with a game plan.
Even after 106, the paint was still very cloudy and hazy. After we wiped it clean with IPA, it started outgasing and fogging up again. Something was wrong with the paint or something was embedded into the paint from a drive through car wash, etc... Usually 106 finishes off superb on hard clears, but this paint was outgasing something. You wipe it clear, and 10 seconds it would fog up. Our garage was 70 and dry. So temp and humidity were perfect.
After the whole truck was compounded and polished, we both teamed up with Ultrafina via rotaries and worked it in till the haze went by by. We were both amazed at how friggen awesome UF worked on this truck and how insane the gloss was.
UF saved the day. The paint was so tempermental, we even had UF dust a tad on us. First time I had seen that. To cure the dust problem, we loaded our pads with a great amount to keep it wetter for longer. Problem solved and were smiling at each other as we were buffing, yelling, "this is amazing stuff".
Even if you don't have a 3M UF blue pad, a LC blue works superb.
