Need help/input with 1994 Winnebago RV

Doing a cleanup on our new to us 94 Winnebago. She's in great shape but obviously due for some color correction and love. The bulk of the cleanup is going great my combo is a Flex (don't know the model), Menzerna 3in1, and some blue pads from a local detail supply house. Anyway the base tan color is coming out great but anytime I get around a colored stripe or painted section everything turns into an instant black mess that is a real pain to work off. I can kill 3 pads and 20 minutes in a 2x2 section and it's frustrating to say the least. I'm glad the oxidation is coming off but I think my methodology is flawed?? I've tried different speeds, softer pads, more/less Menzerna, some Griot's compound, spritz with detailer spray hoping the colored oxidation comes off easier but nope. Any ideas? Thanks in advance Jason

I have plenty of pics but the insert pic button is acting weird and won't let me add mutiples or says upload has failed. Could be my cell area I dunno
