You probably are aware that the hood can be positioned completely vertical? Put it in that position,do the forward most fasteners first with a good adhesive[I used liquid nails]. After the front sets up and the shield is hanging perpendicular to the floor,use a razor to put slits in the cover and use a gun applicator to squirt glue under the shield wherever it is needed.Work your way down from top to bottom.A broom or squeege may help while te glue is settng up.


If there are no clips or you have replaced the original pad with an aftermarket item, 3M Adhesives are the best solution. CLEAN off the metal underside of the hood first, then spray it and the pad. Wait a few minutes before mating them. Rub firmly and you should be good.
