I was patching a small hole smaller than a dime. I went to look and find what product would be best. The pen was advertised for spots the size of a pencil eraser. So I went with the .34 oz bottles. I purchased the primer, color, and clear coat set. The color was very close to that of my car (just slightly darker). However, the application of the paint is with a nail polish brush. This resulted in my application having tons of bumps and ridges. I sanded in between coats and then the final coat. After a lot of work it was very smooth (one or two very tiny air bubble spots). The next issue came when I applied the clear coat. Using the brush for clear coat then smeared the (dried for over 1 hour) base color coat. So the ridges I worked so hard to smooth out we’re right back. I was very disappointed with how this turned out. After working on this, not even, dime size spot for many hours, I am finally giving up. I would suggest others to not use the brush and try either the pen or the spray can.
