And, I can say that I have touched every inch of its exterior...
Yesterday afternoon and evening, I began by washing(scrubbing) the roof and all the roof parts, to include cleaning the dirt from the gutters.
I then proceeded to do a full exterior wash and dry.
After that I applied Meguiar's M6332 Flagship Premium Marine Wax with a Porter Cable Orbital polisher to the entire trailer. I hand buffed it all off. I put three coats on the front and one coat on the rest of the trailer.
It turned out great. The optiplan siding shines better than it ever has. It has a deep gloss, even for white. I apologize for no pictures, but it was too dark to get a good pic last night. I will get a few soon.
My arms and legs (from the ladder) are burning this morning.
Regards,
John
