I wanted to use Brennan's. Emailed about shipping to Canada. No reply.
Hence, the kitty litter.
I'll get back to you in a few years about whether the Ross and Atlas track rust. Seeing as how I have the two side-by side, it should be a good test. Rather doubt it. It's not in a damp basement though. IMO, ANYTHING ferrous will rust in a damp basement over the years. Certainly my tools have done so in some 30 years!
Cost of litter? Essentially free.
Cost of WS? For me, delivered by mail, about $2CDN per foot! (Shipping pretty much doubles the cost. Depending on the amount ordered, it can be even more! )
Which "looks better?" Probably a matter of opinion, depending on colour choice.
Still, were I able to get commercial ballast at a price I didn't feel was just over the top, I would have done so. International shipping used to be of not much concern, but the last few years it's frequently shipping costs that kill a purchase outright! This is particularly true with weighty or bulky, rather low-cost items where shipping can exceed the cost of the product.
It's shipping that drove me to kitty litter. That said, I'm happy with how it looks.
