What did he mean by solid paint though? I vaguely remember it being described for use on single stage paint and specifically being warned away from it when I was looking at zymol. But its not my place to say you can't use it.
You're correct, it no longer makes any mention of clearcoat etc in the blurp although this is telling
"Rouge Wax has been developed to assist in the colour correction of red painted vehicles"
and this is what was sent to me:
You’re right in thinking your Trophy has a clear coat finish which means that I would not recommend the Rouge wax for the best finish. Rouge is primarily designed for older cars with fading red paint.
