Abstract: In a system for treating object surfaces, a first and a second object hanger, each comprising a plate and a shaft, are mounted upon an object such as a door that requires a surface treatment such as painting. The mounted object hangers may be placed into supporting braces on a treatment apparatus, whereupon the object can be rotated into a desired position. A positioning attachment upon each supporting brace selectively maintains the object in the desired position. Following surface treatment, the mounted object hangers may be placed into storage braces on a storage apparatus, such that any treated object surfaces may dry or cure. One storage brace includes an anchoring insert, which keeps an object hanger, and hence the object attached thereto, in a predetermined position. The storage apparatus may accommodate multiple objects in a side-by-side manner.
