This is a Hydrospa shell, they went out of business in 2007.
20 years is supposed to be the general life of an acrylic shell, to the best of my memory.
I noticed about a round roughly one inch darker space, circled in red on the attached pic, and several much smaller places nearby.
My question is: There anything that I can practically do to extend the usual life of the shell? I'm wondering if some sort of acrylic patch can be overlaid?
Or is it better to just bite the bullet and buy another one? or wait till it starts leaking or another pump bites the dust.
I do really like the tub and how it's configured.
Couldn't figure out how to attach the pic
