Four types of clear coating systems which include a newly developed system were evaluated through sunshine carbon arcs irradiation, outdoor exposure, and exposure at elevated temperature. Color difference, residual gloss, and specific reflection spectra within visible layer were measured during these aging tests. Cross-cut test and SEM observation were also carried out for some specimens. The new clear coating system utilizes a new type of fluoropolymer and polyethylene-glycol methacrylate solution as a top coating material and a primer, respectively. The new system shows higher performance than an existina oolvurethane coatina svstem in everv test item.
