I'm about to Herculine some body parts on a Jeep, and I'm wondering if you normally when doing body work cover up threaded bolt holes or paint over them? Is it difficult to put in a bolt if there is paint in the hole?

Herculine is rubber brush/roll on paint. Is it any different?

    Do not paint over bolt holes. You will regret the pain you create for yourself. Commented Jan 9, 2016 at 3:26

    Are you talking about holes with threads or just blank holes? Threads will cause you problems; blank holes, no problem. Commented Jan 9, 2016 at 5:10

    Painted bolt holes is nothing running a tap through them won't fix. Commented Jan 9, 2016 at 16:17

Depending on the bolt hole tolerances you start out with, the paint may prevent the bolt from screwing into the bolt hole.

It's not that difficult to avoid the problem - plug in a rag, tissue paper or something that acts as a barrier to the paint. Once the paint is dry, pull it out to leave thread that is unscathed.


How about taping off the hole with painters or masking tape then, remove the excess tape by using a razor blade and cutting around the outside

  • Seems like if you cut away the tape so that only the part covering the hole is left there would be nothing left to hold the tape in place. Commented Apr 20, 2019 at 0:07
