I saved a lot of my pulls (some not too airtight honestly) than threw them all together in a gallon jar poured naptha than evaporated for some nice shards in a pool of yellow oils.... I was acctually surprised I pulled out plant oils with naptha as usually I never get oils from q21q21 tek like a STB lye tek.

Call me out if needed, but also remember to treat others the way you would like to be treated
