Hmmm, I don't tend to run into this issue. I just tape the trim and cover the glass with some T-shirts. As far as the crevices, I'd try to lay a strip of tape inside the crevice. Ex: Open the hood and tape on the "rain gutter" where the bolts/screws hold the quarter panel on. Is this the area you're refering too ? :nixweiss
Otherwise, as mentioned above, there may be too much product being used.
I've been painting an entire new 2nd floor......it's been killing me to actually use 3M's painters tape for....painting !!! :faint:
