Thanks, Jerry. I bought the Zinnser 3# cut of clear shellac. I used denatured alchohol to cut it to 1#. The boxes I make are from a lot of exotic woods. I could never bring myself to flock the inside of a zebrawood box. As I stated before, I will go back to practicing with shellac. I just have to keep production rolling for now. I appreciate the photo diary of how you fold a rubber. I've been using cut-up pieces of t-shirt wrapped up in a square of t-shirt. Maybe that's something I need to tweak as well.
Thanks again,
Kevin

lac bug wings !! shellac Is an old story, we in the modern day want to know what these compounds are.. If one wants to play with timber finishing and make it last

Meaning:

Once it was commonly believed that shellac was a resin obtained from the wings of an insect (order Hemiptera) found in India. In actuality, shellac is obtained from the secretion of the female insect, harvested from the bark of the trees where she deposits it to provide a sticky hold on the trunk. There is a risk that the harvesting process can scoop the insect up along with the secretion, leading to its death. The natural coloration of lac residue is greatly influenced by the sap consumed by the lac insect and the season of the harvest. Generally in the trade of seedlac there are two distinct colors: the orange Bysacki and the blonde Kushmi.

When purified, the chemical takes the form of golden yellow/ golden brown flakes, this possibly providing the basis for the "Wing Source Story." Shellac is a natural polymer and is chemically similar to synthetic polymers, thus it is considered a natural plastic. It can be turned into a moulding compound when mixed with woodflour and moulded under heat and pressure methods, so it is classified as thermoplastic. But old mouldings tend to become thermoset; that is, they suffer chemical reactions over time and are no longer fusible.

I do not use other sealers Shellac is by far the best sealer and preserver for indoors and outdoors if its waxed well.. Clean cotton sheets linen and meths and a lot of time if you want lust from your work

Is spar urethane like Polyurethane ?

Polyurethane is for boats I find on good timber and works we have done it clouds over time I mean 10 years but it just never really holds its look..

There are my tips in no way are they the right way I just put it this way after 10 years or more of playing with Exotics and common timbers.

Cheers!

As I have said many times,if shellac were first used today it would be hailed as a WONDER finish.
