thanks Arrow5
i have built many a KielKraft Ajax and Achilies myself... ( young-uns will have to google that one

)
i am aware of the shrinking attributes of differnt tissues and dopes. but here i am all those years later trying something new..
i want the tissue for covering, reinforcing, and waterproofing models made of Depron foam board.. a relatively new material to us model makers
no shrinkage required, and the tissue will be applied using water based polyurethane matt varnish, it can also be applied using epoxy laminating resin as used in glass-clothing
thats the beauty of our wonderfull hobby.. there is always some new material or technique to learn and master
