Not all products beaded water. I don’t know the significance of this but observed and recorded it anyway. The products that did not bead water can be seen below.
After 2 hours I observed the samples. The controls were already exhibiting signs of corrosion. White spots are the result of the salt left behind after the water evaporated and does not indicate rust, just dried salt.
The plates spent the night outside and it was quite a night. Temps in the upper 30's, a storm rolled through with wind gusts to 30 MPH and on and off rain. 24 hours after each product was applied to the plates they were observed for signs of corrosion.
**NOTE** Before I go further I will state that during the process of applying the products to the plates, I had to hold the plates by the very edges. The last contact with the plates was along the very top edge as I pushed the sample into the foam board. Some samples took considerable force to place them in the foam. For this reason I will not count against the products that are essentially corrosion free but exhibit corrosion along the edges where otherwise the bulk of the surface is corrosion free. The edge rusting is a result of my handling the samples and removing the product.
Here is sample board #1 after 24 hours
