Rand-O-Proof is a non-tautening nitrate dope specially formulated for the first coats on Ceconite polyester fabric. It is also used to apply finishing tapes and to pre-coat large surfaces of wood or metal that will be covered with fabric. Pre-coating wood or metal with nitrate dope promotes adhesion and helps prevent pinholes in subsequent coatings. Rand-O-Proof is tinted transparent green for visibility upon application. Nitrate dope is always applied as a first coat to Ceconite; butyrate dope of any form will not stick to polyester fabrics

Packaging: Quarts, gallons, 5 gallon pails and 55 gallon drums.


One thinned gallon covers approximately 200 square feet with one coat. See material estimates in the rear of the Ceconite Procedure Manual 101 for the amount suggested for specific aircraft.

Thinning: Thin to spray viscosity with 286 Nitrate Thinner usually one to one.  


For best results, brush on the first coat of thinned Rand-O-Proof. Spraying the first coat will result in poor penetration of the fabric weave and subsequent poor adhesion. Ceconite polyester fabric will not absorb liquids; therefore, the first coat must encapsulate both sides of the fabric for proper adhesion. The best way to encapsulate is to brush the first coat; when done properly the mechanical action of brushing wets both sides of the fabric with no runs on the inside surface. Avoid inside runs, they may show when the aircraft is finished. Tapes are applied with Rand-O-Proof thinned one to one. Do not add any type fabric cement to Rand-O-Proof when applying fabric tapes; doing so will degrade long-term tape adhesion. Once tapes are applied, two additional coats of thinned Rand-O-Proof are sprayed over the taped aircraft surfaces.

Dry Time: 15 to 30 minutes depending on temperature and humidity.

Shelf life: 2 years unopened.
