I can't say all but SOME paint and fabric additives are just a warranty scam.the money isn't in the product or the application...its in the warranty. They put scotchguard or similar product on your interior and a wax or paint protector on ext. and hope they never hear from you.if so ...they win.if you file a claim and it costs them less than 1700 or so to fix them they still win. If you are like most and never make a claim or sell or trade...they win.i am not saying the warranties are not worth it but You have to successfully file a claim or claims for them to be worth it.read the fine print.
