I had several products in mind to do my truck bed when the truck arrived. I don't remember the names of the others since it has been 6 and a half years.
I used Herculiner because it went on sale at a local auto parts box store. I got two gallons for some thing like $85.00. I followed the directions to the letter on the can to apply it. I used the roller and brush that came with the product to install it after tapeing over every place
I DIDN"T WANT IT. I've slid bottom boards with bee hives on that bed for 6 years now along with lumber, tractor parts, firewood plus a couple loads of stones & rocks. The coating still looks great on the bed its self and most of the tail gate. It is showing some signs of wear on the leading edge of the tail gate which I will be touching up as soon as I get the last ofthe honey supers installed and have a fee minute.
I still have some in the can after 6 years that is still good. Store it with the lid down so air can not seep in.
I also used it on the mud flap extentions for the truck. It also still looks good despit our living on a gravel road and having to travel mostly gravel roads to our out yards with the bees.
There are close to 110,000 mile of stones, pebbles, ice and salt that have blasted it.
Would I buy the produce again? You bet I would. I would only apply a third coat to the tail gate and a forth on the leading edge.
