Another joke. Lewm, I'm on your side on this one. Spraying anything on your record is a bad idea and it will not stop the static problem neither will grounded mats. A mat will only discharge one side of the record, the wrong side. There is no magic in this. You have to have a path to ground from the site that the static is being produced. The stylus in the groove. Static electricity is terrible for records because it draws dust like a magnet which you can prove to yourself by holding a record you just played up to a light and you will see dust fly towards the record. The dust can become embedded in the groove and held there so your stylus can grind it into the groove instead of pushing it out of the way. Besides the grounded sweep arm the next best thing for record hygiene is a dust cover.
By the way take a meter and see if your "grounded mat" is actually conductive. If it is not it would even discharge the side of the record touching it.
