[Alumin8]

Curious that you have this problem today. I have noticed the same type of cracks in my bathroom. I have all of the aluminum trim and inserts but damaged one slightly removing it to reach the rivets for removal. I will try for a quick repair but if that doesn't work, I am going to make a laminated counter similar to the cook are out of 3/4 in plywood and laminate of my choice. In my last trailer, I tried to repair and finally had a friend who worked making boats in Tarpon Springs, FL make a mold of the old counter and fashion a new one. I worked great but hardly worth the trouble

Good luck. I'ld be interested in your solution. Keep everyone posted
