Just picked up an old 70's mini bike. The seat is vinyl and in pretty good condition with no cracks. What can I use on it to ensure years more of use with no cracking.

 

I use Mothers Protectant, but any quality product like Vinylex will also work -- don't skimp on price.

 

I use GOLD CLASS™ VINYL CLEANER & CONDITIONER

Special conditioners help prevent drying, fading, or cracking and offer UV protection to reduce damage caused by the sun
For best results, spread Gold Class™ vinyl protectant evenly over the surface with an applicator pad and remove any excess product with a terry towel

Good Luck
