Default Is cutting off the excess RTV off asking for trouble?

I finally got around to installing the new upper oil pan for my VQ35DE. I am also cleaning the motor and painting it. Since I am spending so much time on cleaning and painting the motor, I was wondering if I let the RTV cure for about 72 hours, would it be ok to cut the excess out very gently with a x-acto knife? Or is that a terrible idea?

I read on other forums of people cutting the excess off and they said it caused leaks. ANY insight would be greatly appreciated!

If it were mine, I wood want to make quite sure my seal were good 1st. If ok, I don't see any reason you can't trim it all back to mb 3mm away from mating surfaces. gl, let us know how it works!

I would leave it alone. I've heard too many horror stories about cutting the excess off and causing a leak. I've always left it alone just because of that and luckily have ran into very few issues.

I'd be worried that if you have that much squeezed from the outside edge that you've got a similar amount on the inside. That's all I'm going to say.
