To touch up a large area I would suggest a air brush . Or maybe not , I would def use spot putty (single part 3M) first , though . For the white , don't know , because I have never seen it for real . From the picture it looks white / white . Where my 86' is almost a off/ white .
TX is yours a 87' or 88' ? 87' Marine grn . 88' Teal grn. .
