Clean- refurb- color enhancing product safe for plastic kayak?

Submitted to Product Chat

Hi- I noticed today while rejuvenating some planters that our plastic kayaks are sad looking, faded and dirty from age and storage.

Are your rejuvenation products for plastics ok for a partially submerged boat like this that would be exposed to lakewater and waterfowl and fish?

Not sure if its possible...if theres any product out there —to help refurb our boats diminished appearance- caused by uv and age damage thats safe?Thanks for any advice you can share!
