After five hours we applied the second coat of POR-15. The second application took about an hour and a half. We definitely see the advantage of having two colors. It was very difficult to see where we had applied the second coat and where we had not. We only used one can for the entire second coat. I definitely applied it too think in some parts with the first can.
We just placed our next POR-15 order. We are hopeful we will receive it by this weekend. We ordered two POR-Patch tubes and another six pack of POR-15, this time with 4 silvers and 2 blacks. I found the POR-15 data sheet, and it is well worth the read because it mentions that their silver actually contains flakes of aluminum and is designed for metal strengthening. I wish I would have known that before and used it on my driver's side floor pan that was rusted. It was a little maddening because we scoured the POR-15 catalog and web site researching what we need for this project and never saw that mentioned. However, now that I ordered the silver I can coat the damaged area of the underbody and strengthen it underneath. I also plan to use some of the PowerMesh on the bottom of that floor pan.
