Yes it is!!We called it "matte" or "baço"!!I live near the ocean so its very common cars this age look like mine and mine was one of the good ones!!Even newer cars 2/3 years have rust!!The dash is my cancer its made out of cardboard and staples GL and GHIA have plastic ones but does cars are impossible to find here in Portugal and the ones i´ve found were in pieces and without the dash!!I´ve found a good condition xr but the dash was completely rotten!!Next step is lowering it and the interior but without the dash !!
