Rep Power: 382

my sideskirts is not staying down very well.
the little corner just keeps becoming unglued after about a month of staying down nicely, it's not that big of a deal but i thought if i want to have a nice car i better do everything properly. i have taken them off and cleaned and retaped them back 3 times now, takes about 2-3 hours each time. the tape that i use is the 3M automotive tape, very good stuff but the damned skirt is way too stubborn to be held down by the tape.
i've tried "baking" it under the sun since this is made of PU and after a month same thing happened. i am ready to seek professional's help.

a friend of mine suggested that i use a tac gun(??) to hold the skirt to the body but will make a little dent, this might be my last resort.

anyone help?

PS i have the g5 skirt
