Thanks for the info, might try it, but salt is the easiest component to remove in the "solution" on the roads in the winter and I think it is the "tar" from the roads that is the tricky one? Tires with studds are evil! 👿
I contacted them by email and they told me that:
"The website is under construction. You can visit www.theragcompany.shop or just send us an email with the requested products and we will send you an invoice."
About the prices, my local dealer has about the same prices so I think it is the cost of transporting that makes the prices to be higher?
