Customer Questions
What is the ideal trailer size and weight capacity? What is the ideal pickup truck size and weight capacity and can this unit be mounted sideways in the bed of a pickup truck and if so what size pickup truck?
Ideally a 6’x10’ with minimum of 4,400 lbs full weight capacity. We recommend a dual axle trailer but a single axle will be fine as long as it has a 6000 lbs axle. Ideally any pickup truck with an 8' bed and 4,400 lbs minimum weight capacity.
Why add a transfer kit?
The transfer kit accessory is available and sold separately. It allows you to transfer sealer from drums, tote tanks or bulk tanks for $399 when purchased at same time of order or $450 if purchased after separately.
How do I remove or clean off the sealer stain when it dried out?
It's best to always have a bucket of soap and water handy. If there are stains, try an orange based hand cleaner available at any auto parts store. Apply to the overspray and let it work in for several minutes before removing with soapy water. You may have to repeat this application several times.
