Is it possible to install M5 side skirt without punching a hole onto the body?

[anakin]

I've had a bad experienced trying to drill holes onto the lower body for M5 side skirt installation before...misaligned and oversize hole(OMG!!)...does anyone here used other method? Gum/silicone or something....I really not into drilling anymore...:dontknow:

question is how strong will the glue/silicon hold the side skirt?? u wouldn't want to lose a sideskirt while driving on the highway and hit another car in the process...
