LP jackett maintance and fix?

I would like too get in to a tread that I am not to sure anyone ever started or even had spoken about, and that is the fixing of torn record jackets with proper maintance of them, and not the LP itself which has been spoken about much here. I have found by using a pledge type of spray wax, helps greatly in the cleaning and the bringing back of that lost luster with many lament type jackets. I have heard that glass wax is also a fine product for this use, and for torn and seam splits white glues such as sobo work very well and fast. I'm sure there is an audiogoner who works in the resturation of books and documents, who might guide us with the use of better working materials.
