The intent of this investigation was to determine whether aluminum signs that underwent the hydrostripping process would meet ODOT’s specification for sign blanks based primarily on whether the anti-corrosive coating was removed during stripping process. Due to a change in the anti-corrosive coating applied to new sign blanks, which resulted in two types of coatings in ODOT’s sign inventory, the outcome of the investigation was a set of baseline measurements for the hydro-stripping process.
