Painting front cap on a 5er

I've had two of them painted and one rear cap. Don't have it done outside. Don't know of any mobile shop that will do it. Look for a shop that paints Big trucks and buses. An RV dealer most likely won't have a big enough paint booth and will send it out, then mark it up some more. A quality automotive base coat/clear coat paint job will hold up well if properly prepped. I paid in the neighborhood of $1500-2000 for mine. It was expensive but well worth it. Good luck
