Within the generic categories of rail car exterior coatings, there are significant variations in performance. Therefore, testing is required to select coatings that will give the best performance. Outdoor exposure tests produce meaningful results but require months to years to obtain results. Therefore, four common accelerated test methods were evaluated to determine how their results would correlate with the results of outdoor exposures with respect to gloss retention.
