Hi all,
After gluing the canopy of my airbus a400m to the fuselage with white glue there happened to be gaps where the canopy and fuselage meet. I wanted to apply putty to fill the gaps, but I am worried that the putty will cause the windows to fog up.
The putty that I use is Bondo Spot and glazing putty. Will it cause the clear parts to fog up?
Thanks
I don't know if your putties would cause the reactions that produce the frosting on clear parts. But you could always use the same white glue you used to attach the parts, to fill the gaps, too.

Bondo putties are polyester based IIRC, and they will fog the hell out of your clear parts just from the vapors coming off of them as they cure. Better to use an epoxy putty like Apoxie Clay for a permanent solution. You can use plain old water to smooth that down and remove the excess, so it also eliminates the sanding you would have to do with Bondo putties.

If you have any perfect plastic putty, you can use that as well, and remove excess and smooth with a damp qtip.
Any product containing volatile solvents could possibly haze clear parts.
Alcohols, not so much...but stuff like mineral spirits and acetone (to name but a few) do not usually "work and play well with" materials like styrene-type plastics.
Acrylics and plastic-based puttys are safe, as are some varieties of epoxies. The latter should be tested first, just in case.
Note that clear-part fogging from CA adhesives can usually be removed with denatured alcohol, since it tends merely to rest on the surface. More volatile solvents, however, can actually etch those surfaces...leaving sanding/polishing or replacement as (usually) the only effective options.

Bondo Spot putty (Bondo Red) is a solvent putty. Hazing clear is a threat
Bondo Pro is a 2 part catalyzed epoxy putty. Less of a threat
I think I would go with Milliput, Perfect Putty, or Vallejo which are water smooth & cleanup

Another vote for PPP. You apply it then let it set for a few minutes and use a water dampened q tip to get a smooth fill area. Bondo will fog the clear parts for sure.
