From another manufacturer that uses similiar material: THIS IS NOT FOR HOBIE'S !!! - but could be helpful because the materials are similiar.

Q. How do I get my registration numbers to stick to my boat?
A. 3M makes a product called 94 Primer that should be wiped onto the area where decals will be applied and allowed to evaporate before applying the decal.
Q. What happens if I hit a dock or a rock with the boat?
A. The boat will flex and absorb the impact instead of cracking, splitting or denting like an aluminum or fiberglass hull. (A test ride is a good time to demonstrate this and as well as how the boat absorbs the impact of beating into waves or bouncing off of docks.)
Q. What if the boat gets scratched?
A. Since there is no gelcoat, the color is solid all the way through, much like a Corian® countertop. For a small scratch, simply sand the scratch out, starting with 400 grit sand paper and then finish sanding with 800 grit. This will leave the surface dull. Bringing the shine back to the boat can be done in two ways. (See below.)
Q. Can the sheen be restored after sanding?
A. Yes. Try one of these methods:
(1) Polish with a dry, clean buffing pad and an electric buffer. Buffing action will create heat that will bring the sheen back to the surface.
(2) If you don't have a buffer you can use a heat gun. Simply warm the surface until you see it “gloss” and take on a slightly wet look. Do not heat too much to cause it to discolor.
Q. What if it is a large gouge or hole?
A. Large abrasions or holes can be easily filled with a plastic welder and some replacement material supplied by your Triumph dealer. Once the area has been filled you can then sand it smooth using the same method as above.
Q. Can I rig anything on the boat (e.g., cup holders, rod holders, antennae)?
A. Yes. In fact, it is similar to adding accessories to FRP. Most items should be fastened to the material using self-tapping screws. Make sure to “bed” all fasteners with Rule (Sudbury) Elastomeric Sealant. If it is an item that will see large loads, you can fasten to the hull using a Toggler toggle bolt, a stainless steel anchor that is permanently fastened in the hull. Many marine suppliers carry these. If the item needs further support, you can cut a hole for an access plate and back up the installation with a backing plate. We recommend you call the factory to make sure you are not in an area of structural concern. (Toggler’s have a pull-out force of about 400 lbs.)
Q. How are cleats, bow eye and stern eyes attached?
A. Hardware is mounted using molded-in inserts. These inserts are chromeplated stainless steel, have a backing flange and are molded right into the boat. (The pull-out force for each insert is up to 1,200 lbs.)
Q. What happens when water gets inside the hollow hull?
A. The hull is almost completely filled with closed cell-foam so there is not much space for water, but there are drain plugs on the boats to check for and drain water.
Q. Since nothing sticks to this material, what can be used to bed any fittings to prevent leakage into the hull?
A. Rule Elastomeric Sealant works the best at providing adhesion, as well as sealing. It is available at many marine supply stores and at Wal-Mart. Silicone, 5200, polyurethane or polysulfide sealants should not be used.
Q. Is a warranty available?
A. Triumph has a Lifetime Hull Limited Warranty that covers structural problems.
Q. What are the environmental benefits to this boat?
A. The boat is produced using a zero-emissions manufacturing process. The hull is also 100 percent recyclable. It can be reground and made into another PE product. Of course, Triumph uses only 100 percent virgin material for strength.
Q. If a screw pulls out of the material, how do I fix it?
A. With a Roplene®-constructed boat, the repair is easy. Simply heat the screw over a torch flame while holding it with pliers, dip it in polyethylene powder (supplied by Triumph or a Triumph dealer) and insert it back into the hole. Hold the screw in for a few minutes while it cools; the heat from the screw will weld the screw into place.
Q. What happens if the hull deflects?
A. A small dent or deflection will not cause permanent damage unless stored for a long period of time. The material has memory and will return to its original shape when properly stored. This usually takes about a week, depending on the degree of the distortion. Large dents and deflection can be a problem if the yield point of the material has been exceeded. Prevention is the best cure.
