Unfortunately, not designed for stone chips underwater though.
It will be interesting if you gave the forum an update at some time long in the future about its suitability.
With a name like Epoxy Tar, it sounds as though it may have a resilient surface which would be good.
Stone chips underwater? no but resists chipping the barnacles off

Certainly considerably more chip resistant than Hammerite which I personally don't rate that highly.
The original VC TAR which I brought several years ago was in fact a mixture of Tar and Epoxy and slightly undercatalysed would dry slightly soft but in reality I have found that it stands up to anything when correctly mixed normaly hard.
In the boating world to get the stuff off requires rather aggressive sand blasting.
The latest mixtures have had proper coal tar taken out (might cause cancer!) and replaced with a synthetic tar, I hav'nt used this but all the reports I get / have seen say that it is as good as the original.
I have used it on bits of cars, e.g suspension arms and bits of boat engines, exhausts, steel injection pipes,and the like I have never had to re-apply it

.
Mind there are other epoxy primers which I suspect would do as well in the motor environment and may be cheaper.but they won't be glossy like VC Tar.
