Here's the reply from the company that owns Rain-X products:
Thank you for contacting ITW Global Brands! Unfortunately, for the year, make, and model of your vehicle, we do not have a recommended blade size, which means our blades will not be compatible for your vehicle. This is either because the blade size(s) required for your vehicle are either too small/big, or our blades are not compatible with the arm type that you have. 2% of the vehicles manufactured fall into this category.
2% huh. Wow, are Sonics fall into the same category as milk and the rich
Thanks Rain-X. Next!
Sorry M.E.C.O.
