if you knew the brand of super glue its useful, cause most manufactures sell a super glue de-bonder. worst case tho is it the chemical reaction that takes place that gives off heat (exothermic reaction) that will melt your dash.
if your handy with a stanley blade i'd shave it off to a very thin layer then use some 320,400,600 grits to 'polish' it out.
any mistakes could be repairs with black wax
