Best product for treating old vinyl

I like this for vinyl tops, toneau covers, tires etc.
One Grand Ext. Rubber & Vinyl - 16 oz Pump Spray
I use this for the interior. It says its for tires and works for tires well but really excels for interior treatment. It's water based and doesn't leave the slimy shine like a lot of treatments. Just a nice dry sheen.
