How to test epoxy.
Not uncommon for me to get a tech call from a restoration shop where he has a new helper or painter that has epoxied a car and because they may have three or four of the different colored epoxies on the paint bench he is not sure if it was mixed right or not.
Note the simple test for the SPI epoxy., this only applies to the SPI as there are 100 ways to make epoxy to accomplish certain things.
Duct tape is a useless test on epoxy because of type of adhesion.
Next day with a razor scraper pick a flat surface and try to scrap off in one stroke go to metal and see how much comes off, normal would be 3-6 inches.
Next day go to a new spot and you may scrap off 1 inch or so but do not try where you finished the day before as that will give you a false reading.
Third day pick a new spot and it may gouge to see some metal or just gouge the epoxy.
With this I can tell the guy, the painter mixed it perfect.
If nothing else and may not be needed, just something to put in the knowledge bank.
