I'm looking for recommendations for a paint on bed liner. I'm thinking along the lines of 2 coat epoxy that isn't too slippery and sticks well to a metal bed. Something that will take abuse with logs, rocks etc.
I used a kit made by rust oleum to do the bed on a Daihatsu mini truck, it worked out ok.
The trick is in the prep work, first I pressure washed the bed, second I wiped it all down 3x with xylene using a new rag every time.
Then I applied to the bed with a roller and used a brush for the corners.
I let it dry for a few days and it looked great, but not professional.
As far as rocks and logs dropping on it, I dont know, maybe a plastic truck bed liner would be better for you.
