I hacked away a lot of the -10 cabin cover drainage lip for the McMaster seals and these work fine. They are cheap enough to simply throw away.

I do have some PermaGrit tools - the sanding block is good for finally finishing a straight edge, and the cutting disk works great, but so does the similar Dremel carbide cutting disc from your local hardware store.

Get good at sanding holding the die grinder in one hand and the vacuum nozzle in the other hand.
