Sealant Testing on Metal Stage 1
I'd like to thank those who are providing additional information and suggestions for my testing. These first two rounds of testing were not definitive in any way and there's still lots of tweaking and more options to try.
Please note that I did not "heat cure" the ProtectaClear. I followed the manufacturer's directions.
In order to cover as many bases as I can, I will "heat cure" the ProtectaClear during the next phase of testing as many metal clay users swear by this.
It has also been recommended to heat the metal prior to soaking in mineral oil for greater efficacy.
In the next round, I will also be testing sheet metal along side the metal clay, for comparison.
Thank you all again for your suggestions and support!]
