bag conditioner!!!!!!!!!

ok....so i was at a truckstop and i was looking around at shit like i always to at truckstops when i come upon a spraycan that says...Airspring conditioner...WTF...so i bought all 5 cans and when i went up to the counter the guy says...they dont make this stuff anymore...and i was like...whaat..but supposedly theres companys that still do according to him..so anyways im reading the can and it says promotes longer life for airsprings by reducing friction and condioning the rubber....and it doesnt contain petrolium products so it wont cause bag stretch......anybody else ever seen this shit...ive never seen it before.i cant wait to try it out when my truck gets back from the shop....
