Black out badges question

Ok, I read up on a thread (cant find it again) that showed how to easily plastidip your badges by spraying it on (the badges and truck), cutting out the letter/emblem (with tooth-picks?), then rubbing the plastidip off the truck.

This looks to be very easy and so very tempting, however Im trying to avoid putting platiderp on my truck.

So, I was thinking aboiut doing the above but instead of rubbing the plastiderp off the truck, instead rub it off the letters, paint the letters, and then rub the plastidip/paint off the truck.

Feedback would be appreciated .
