Here is how I covered my Sig 1/4 scale Clip Wing Cub using Koverall and a latex glue/sealer named Mod Podge available from Michaels Crafts and other stores. I used this product thinned with tap water to seal the airframe with. This sealing process started with a sanded airframe and then the first coat applied with a foam brush. After drying a light sanding using about 400 grit paper. Tac cloth this clean and apply a second coat. Let dry and my plane did not require another sanding. Next step use a tac cloth again to remove any dust, then cut fabric oversize for the area your covering. Apply thinned Podge to framework around perimeter of area to be covered and lay fabric on plane while still damp. Apply more Podge as required to hold fabric in place and smooth out any wrinkles before fabric dries to airframe. After this dries trim Koverall with a sharp X-acto or some say a single edge razor blade works better. Make sure that the edge of the Koverall has been coated with the Podge and dried. This prevents most of the fabric fraying that is a real problem. Use a Monocoat iron to iron down the edges of the fabric. Apply more glue if needed under the covering to secure it. I now use the heating iron during fabric application when gluing it down to set the adhesive. This works well but you must clean the iron often and not use to much heat or you will make a real mess! After all fabric is applied I shrink the fabric per instructions included with the fabric. The fabric can be sealed with the thinned solution of Podge, just make sure you use a very light coat or it will form puddles on the back side of the fabric. Takes about 3 light coats to fill the weave. A very light sanding may be required after the last coat and then a final thinned coat. Remember to always use a tac cloth to remove any dust before each proceedure. Your now ready for the latex paint. With no SMELL!!!! I did mine inside in the winter. Words of caution. When sealing the framework your using a water based sealer (Podge) so it will be very easy to introduce warps. You have to plan for this on the light structures such as tail feathers. Also the shrinking process of the Koverall can crush or warp structures as the shrink factor is much greater than the plastic films and even the other fabrics we have used in the past. It does take time to do this, no instant gratification like cover with film and fly covering. Fell free to ask any questions if you would like. Hope this helps.
