Our standard truck bed spray on coating works well as an undercoating, but we might recommend a modified product by custom quote. We would generally suggest a more flexible version of our protective coatings, along with only the lp80 (finer) powder additive when using as an undercoating.
Diamondback Linings tries to offer products through our online store which cover the most popular items, but all of our coatings can be adjusted based on your specific needs. We are never too busy to customize your product if our standard products don’t quite fit.
Do remember if applying any coating as an undercoat, that you will be spraying upside down with limited space. The texture hopper supplied with may of our kits can apply coatings in this position. You can also modify the capacity of your gun easily by using some commonly available parts. Get in touch with us directly at 855-545-4900 extension 902 for sales support for more information.
