Got a flyer from camping world and they now carry silkaflex caulks. The price ranges from $7.19 to $14.39. I don't know the differences. silkaflex 211,silkaflex505UV,silkasil gp caulk,sikaflex 252 caulk,seal adhesive caulk(Black),sikaflex715 caulk. I know uv is sun protection and gp is general purpose. I don't think I would order from them due to high shipping fees. I will stick with lexell caulk as my local ace hardwear store carries it for $8.00 a tube. Are the two caulks like comparing apples to apples?

See yesterdays post on Silkaflex caulk at camping world. I don't know why some of the post is in red ink.
