I got my mfk decals today and i got a question have any of u guys put 1 on the car if u stuck it on the outside of the window how long befor the weather washed it off seeing how it is not really sticky. I got 1 on the aquarium i just windexed the glass and smoothed it out with a i.d. card it stuck pretty good but if i put the sticker on the inside of the car window u know reversed would it stick as good as the side that goes on the tank?
