Talk to me re checking for cracks with cotton balls. I recently noticed that the paint (or whatever it is) on the outside of my Excal limbs is just a bit rougher in several spots on both limbs, approximately in the area where they bend. I can feel it by running my finger over it (feels like tiny goose bumps) and it looks less shiny in those spots. Are these cracks, or just my imagination running wild? How do I check for sure. Has not been dry fired but I do shoot nearly every day thoughout the summer.
