Does anyone have a recommendation for painting the interior of a Hawk gooseneck trailer? It still looks perfect on the outside, but the inside has a bit of surface rust from 17+ years of horse snot and teeth scrapes. I think the paint needs to be sanded down and re-primed before being completely painted again. I also have some replacement padding that I would like to have installed and a screened window that needs repair. One referral for all the needed work or separate suggestions would be appreciated.
