Trying out some shellac from a place in Barcelona. Most likely only of interest people with Spanish/Portuguese connections as the website is in Spanish/Catalan/Portuguese. If you search for "coma laca dalmau," it should come up. (quimics dalmau online). Looks like a small local shop. Cheaper than the online luthier suppliers.
First impression is good. It dissolved as easily as any other shellac. I haven't applied any yet, but it is "behaving" as expected so far.
