Arnesr,

That's exactly the method I follow.

Good to know it works for solid others too.

Coffee - resin, fiberglass, sand paper and cheesecloth - why pay for therapy.

Indecently, I've watched some youtube videos that overcomplicate it - somewhat hysterical if you find them -  unlike the quality links posted here by you and ST.

It's just not that hard - even I can do it.

Thank you.
