Which tool do you use to remove the excess sealant after cap sealing?

The correct choice is to use MPK solvent and a clean cloth for removing excess sealant after cap sealing. This method is effective because the solvent is specifically designed to dissolve and clean up sealants without damaging the surrounding surfaces. The use of a clean cloth helps ensure that the excess sealant is wiped away thoroughly, maintaining a clean finish on the assembly.

Using a utility knife may pose a risk of damaging the surface or creating burrs that can affect the integrity of the assembly. A damp sponge could potentially remove some sealant, but it may not be as effective as the solvent in breaking down the sealant material completely. Additionally, a heat gun could potentially soften the sealant, but it risks causing overheating or damaging components, and it's not the standard approach for removing excess sealant in a controlled manner. Thus, the combination of MPK solvent and a clean cloth is the safest and most effective method for achieving a clean removal of excess sealant.
