Thanks guys for all the good suggestions. I have ordered the 3-M double sided tape and we will try that for a quickie fix?? If it is used under the mat (out of sun) maybe it will last??
I think (like most of you) that the black silicone caulk is the best way to go....Thanks Stan! The only problem I see with opening a large caulk tube is you better use it all as it will get hard.
But, maybe once a year thing might be the way to go with this method.
