I will be shooting some Raptor liner in the next couple of weeks and I'm a little nervous about tape lines on my new paint. Its a 74 Bronco interior I will be spraying. I have been using the yellow 3M tape so far. Will this work with the bed liner? Instructions for the liner say to remove tape after 30-45 minutes. Are there any tricks to getting a nice edge when the tape is removed? Also, I can use the gun that came with the kit or I have a primer gun with a 2.5 tip. I would like to get a smoother finish since this is on the interior. Any suggestions on this would be great.
