HERCULINER product reviewI applied this product to the box of my new truck box. I expect it to be very durable for a long time. Product instructions recommend using the roller for application. I found that the roller is not suitable for application; rather a good natural bristle paint brush is much better at application. Also, thinning the material with Xylene-Xylol will improve the viscosity for appropriate application. In colder temps the material is too thick; and in warmer temps the solvents evaporate too quickly. Thus use of some Xylene is helpful for application.
Most difficult part of job is properly scuffing the surface of the work material. Steel wool or sandpaper are more effective than the scrub pad included with the product.
I had used a similar product on an earlier truck box 10 years ago, and it was very durable. These are good protective coatings and much less expensive than LINEX and other professionally applied products costing $500.
This product is also suitable for protecting wheel wells and unpainted differentials from gravel damage.
