Devcon is an epoxy and probably not that good for covering open structure models. Did you mean Diatex ? If so it is sold by Skysport Aviation and the grade you need is Diatex 1000. it comes on a roll 60" wide. Skysport also sell the low taut dope you will need to fill the weave. They also sell a covering cement (Glue) but it I find it too thick and a pain to use so I just use Balsaloc.

Sky Craft is the place, they are in Spalding, Lincs
Diatex is stronger than Solartex and the bond to the underlying structure is better when properly applied and it is more temperature stable so adds strength to the structure better than Solartex. Being 60" wide also makes covering bigger models easier without having to worry about joints. Properly applied I do not think it is any heavier than Solartex that has been sealed ...but .. although it takes no longer to apply that Solartex it does then need several coats of dope to seal it before applying any finish paints.
Sealing Solartex can be done with dope or paint but I am sure there are others who can advise the best products to do this as there is some fantastically well finished Solartex covered models within our community.

Evening Mick - What size wing joining tube did you use 19/20mm ?
Thanks JG
Re: 1/3rd scale ka8b -island models
hi jason
its 24 mm with 20 mm rod for main and 12 mm with 10 mm rod for incedence pin
you thinking of going for one ?

Diatex shrinks in direct proportion to the amount of heat so start at a low temperature (90 to 100deg) and go over the whole surface. Only turn the heat up a little at a time (10deg) if you need more shrinkage. It will take a very high heat but if you start high you will loose all control over the shrinkage.
Under no circumstances use a heat gun as this will ruin the fabric.
Don't forget to dope all round the edges first to seal them before shrinking and work from the middle out to the edges to avoid reactivating the balsaloc and releasing the covering.
