I've started to prime a kit and noticed seams that were quite visible. What is a good solvent to remove the paint that I've added. I painted with acrylics. Looking for a solvent that is not too harsh where it will remove the paint but not any of the details of the kit.

There is lot's you can use , soak it in windex over night and srub with a tooth brush .
You can even use easy off , spray the area and let set for 20 minutes and then rinse it off with clean water srubbing with a tooth brush . Wear a mask and rubber gloves . But if this is just a primer coat you can sand/ fill the area and just respray once agian .

Thx for the tips!!
