I understand that you are becoming weary of the suggestions to repaint. Having said that it's safe to say that you aren't going to polish these (regardless of product, NXT, DACP, AIO or PPCL) and bring the original shine back without shedding some paint. Even with chemical only type polishises the pad or rag will take some of the original color off. If a product as benign as NXT is making your pad red, the finish is pretty oxidized and you have to remove this layer to get back to the original finish. If you were asking me for a chemical only product to try it would have been AIO but even this is probably more harsh than NXT.
