Yellowing 3M 4200
I recently used 3M 4200 sealer to caulk and seal all my rail stanchion fittings and my cleats. I used white because I have a white deck. I noticed today that it is starting to turn a buff color.
Is this normal or do I have a bad tube? I did this less than a month ago and just today noticed the change from white.
