Are rubber rejuvenation products worth it? Do they work/improve the lifespan of the component?
Several years back I saw a Scotty Kilmer video using ATP AT-205 for several car rubber components. The product itself does state - Rejuivinates all rubber seals & gaskets in engines, transmissions, power steering, differentials and hydraulic systems. Does not contain petroleum distillates, will not over-swell or breakdown seals.
Being based in the UK I am unable to get it, without spending a fortune. Few weeks back I came across a video with someone using 303 Aerospace Protectant, this being readily available in the UK.
Allegedly this works similar to the ATP AT-205. The product itself does state - Great for use on a variety of surfaces such as: vinyl, leather, plastics, synthetic & natural rubber, PVC, gel coat & fibreglass.
Is there any benefit to using any such product on rubber suspension components? Tie rod rubber boots, ball joint rubber boots, CV joint rubber boots, engine mounts? I'm wondering some of these rubber components can harden over time, so wouldn't rejuvenating - potentially softening them up a bit destroy/damage them earlier?
Thanks.
