What do I use for roof gutter? (1 Viewer)

[890man]

I'm planning on removing the old cracked sealer in problem areas on the gutters to prevent any typical pig roof rot but I'm not sure what to replace it with. I just want to make sure I dont have any issues down the line. I'll find a good supply house in my area but I thought I would try you guys first. Thanks

Roll on, or better yet spray on liner. Thick though.
