GRP cleaning and protection

[bobbyj]

Folks - some advice when I pick up my Can Am soon regarding bodywork cleaning. I am sure this has come up before but the search function led me down a few non-helpful rabbit holes...
First is cleaning the GRP - what's the best product? Lots on the net re marine applications but can't find much on car GRP but may be the way I am searching. So any help gladly received. My car will be (is!) black GRP.
Second is I am considering a clear vinyl wrap (3M or similar) for the front clam to protect - good idea/bad idea? Anyone done it and if so was it worth it?

Thanks in advance
