Rejex is a nice durable sealant..I got a 4oz sample 2 years
ago...I used it on paint a few times but a bit to glossy for me...lol...its like Klasse SG....super gloss but a sorta sterile look..but lasts a long time...its a great wheel sealant also....it does take a beating and still look good....
I believe it was designed to use on turbo fins on jet engines to retard carbon build up..so it must be durable to stand up to them extremes....
Now this would be the sealant to use instead of JS109 if topping with a wax...lol...it does protect and is very high gloss also
