Hi everyone. I have an 09 G37s sedan. It has some cosmetic damage I assume caused from age/sun damage/wear and tear and looking for help on where I could get replacement parts or possibly repair. I have attached some images. The dash is starting to crack (I hear this is a common issue). The exterior door trim (in-between front and rear doors) are showing some wear and tear as well. Can this be sanded and repainted or should I just replace. Where could I get the replacement trim. Thanks in advance.

 

The pillar trim is vinyl I believe. You can peel it off and rewrap it. That trim on the side of the dash you can remove and reglue it, or get the updated one from another car which is just a solid plastic peice. The dashboard is going to be difficult but there are some filler products to at least make it look somewhat better
