Polyurethane Finishes

RandolphRanthane High Solids

Polyurethane paint sticks well to everything, so you can use it on fabric, primed metal, and fiberglass. It gives a high-gloss “wet-look” finish that is impervious to chemicals and staining. You can use Ranthane HS over the fabric and metal parts; all surfaces will have the same gloss and uniform look. Ranthane HS requires only half the catalyst than the original version of Ranthane products, or a 2:1 ratio. The original version of Ranthane products are no longer available.

Ranthane is flexible enough for use over fabric and has an outstanding service record. You can also paint primed steel tubing that will come in contact with fabric cement and dope with no fear of lifting. The down side of Ranthane polyurethane is that it is more difficult to repair than dope (you must sand it off), and it cannot be rejuvenated because it is impervious to solvents


A tough, flexible, solvent, chemical, abrasion, and weather resistant high gloss, two part polyurethane recommended as the best quality fabric finish over Poly-Fiber covering materials, and all primed metal and glass fiber composite components on fabric-covered aircraft. Also recommended to refinish suitably rejuvenated nitrate and butyrate dope-coated aircraft fabric surfaces, all old sound finishes on metal and glass fiber aircraft components, old finishes on glass fiber or metal boat hulls, automotive, truck, and industrial equipment. Cans are 3/4 full for the addition of catalyst.
