I had a heck of a time getting paint in these slots with a brush. Then I tried panel line accent. I wiped them with a used bounce sheet to get rid of static cling and got rid of as much excess off the accent brush as possible…and still got a large drop!? Then I tried this CA glue looper and it worked pretty darn good. The amount of accent available on each application is very limited. I’m sure it could be used in other locations also.
