Ugly is only skin deep...

I went to Princess Auto on the weekend. For you "South of 49'ers" Princess Auto is like a Canadian version of Harbor Freight. The kind of store any man would love to be locked inside overnight. I bought five of these wire-brush wheels you can see in the picture on my grinder. These things are usually $20-$30 at Canadian Tire or Home Depot, on sale at Princess Auto for $3.99. I'm sure the quality isn't the same, but since it took four of them to clean up the trailer frame I'm sure I still saved money even if one of the "good" ones would have done the job.
