Default dope not sticking

I had to replace a panel of solartex on my beaver using buytrate clear w/ talcum to fill the weave and it''''s not sticking to it. Tightens up and lets loose of the surface. HELP!!!!!

Bad news I have had the same thing happen [:@] The dope seems to disolve the glue backing on the covering and it lets go. Not compatable with each other unless put on in thin coats where it dries before it has a chance to disolve the glue. I would check the rest of the covering to see if is stuck [&o]

No thats not it. The dope isn''t staying stuck to the solartex. The rest of the plane was shot with nitrate w/talcum and is fine. Now that I''ve swithched to buytrate without nitrate under this showed up. Do I need to udercoat w/ nitrate or is it a problem with too quick flashoff of the thinner? Khelsea

Your on the right track. Add a few drops of Butyrate Retarder (or MEK) to your dope. That will slow down the drying time and allow the coats to bond to each other.
