hello Tim
(there are many such similar questions in the other forums too)
I'm using those small spray cans from Tamiya, Gunze etc which shoot finer sprays than those regular DIY cans with larger spray nozzles...perhaps this is what you used?
again, I recommend Tamiya (I'm sure there are other brands but its just that I've been a Tamiya collecter for a long time) produces tapes in various widths but I sometimes cut them narrower....again, please dont be tempted to use those cheaper DIY masking tapes which are not meant for such fine small areas.
Dont throw you tape away, practise on a plastic surface or something and see if its your paint or tape or patience that was giving you this problem. For flatter surfaces, I do sometimes use those advertising stickers (they are much thicker and sometimes are just PVC coated paper so be careful)
Paint seeping under tapes does irk me too....
you must carefully check and press them down completely...
most often its due to spraying too much at a time....you have to be very patient and spray one thin layer at a time....no luck needed
