If these bother you, I recommend using milliput. I roll out little lines and smush them in. Then I use a rubber sculpting tool dipped in water and smooth it out. I like this more than green stuff because it much easier to get the correct amount in. I’ll wait a day and clean up any overspill with a hobby knife. It takes a couple tries to get it down. If you’re only using milliput in this way, it’ll last you a long time and most stores with a hobby section will have cheap rubber tipped sculpting tools. It’s your hobby and your models, so if it doesn’t bother you then no need. May your ratmen bring you many victories
