Has anyone had success gluing on clear plastic
windows/canopies while avoiding the fogging, etc.
problems associated with CA?

RC56 is OK, but I like the bonding strength of CA.

If you've used CA successfully, tell me how you
did it.

Thanks.

You can use oderless CA with good results however I have never had RC-56 fail, I do leave an area unglued or drill a hole in rear edge to let expanding air out. I realy think this is the reason for no failures. A friend of mine glued a canope all the way around and it just popped up in the sun (would have blown off if in the air). Do not use regular CA it will fog the plastic.

The odorless will not fog the canopy.

If you really want the best canopy glue of all, try PFM. It was marketed by Innovative Model Products. PFM was a hobby product which was really only a repackaging of a product called E6000. I have found E6000 to be available at craft stores. This stuff looks like silicone but smells entirely different and is much better as an adhesive than silicone. When dry, it is very tough yet remains somewhat flexible. Great stuff.

I once had a P-39 which had a canopy glued on with PFM to the monokote covering on the fuselage. This plane went straight into the ground at well over 100mph. The impact folded the fuselage(and the canopy) like an accordion yet the canopy stayed stuck to the monokote without letting go at all. I too once used R/C 56 until I discovered PFM/E6000.

In the back of Sig's instruction booklets they say to spray on some accelerator to prevent fogging. Of cource youll have to work fast.

PFM, greatest glue they have come up with for canopies, as well as lots of other things, model related and not.

Would "Goop" be the same kind of stuff as the PFM referred to?

Goop is definitely not the same as PFM. If your hobby shop can no longer order PFM, a product called E6000 is the same as PFM and is available at craft shops. Here in the St. Louis area, it can be found at a large craft store named Michael's. I am not sure but I think this store is a chain.

Here is a source for ordering the E6000 if you cannot find it locally. PFM is really repackaged E6000. The best part is that E6000 is much less expensive than PFM.
