If I cover my PT20 with silk from a fabric store and use dope ONLY around the edges to apply it, can I later use my iron to shrink it without any affects from the dope?

If I am lucky enough to find silk in the colors I want all I should need to do is apply it as mentioned above, then coat with a few coats of butyrate dope to fuelproof it. RIGHT???

Or would it be alot easier to use stix-it and an iron, then few coats of butyrate dope to fuelproof?

I prefer the dope method because the dope would hold it in place better as you iron it taute. IF you CAN iron over dope.
