Anyone find a non-crazing - fogging plastic putty?

[SpeedShift]

Years ago, I needed to use a putty/filler for a gap next to a clear plastic window...(actually a canopy but that's beside the point).

I remember using a red clay like putty in a small tube that was non crazing and did not fog the clear plastic even though it was right next to the clear plastic.

Tube is long gone, and I can't remember what it was or find anything like it.

Has anyone used - or found something similar?

Lets start with which specific putty that you use is crazing plastic for you?

While I have not heard of it before, many 1-part putties do use "hot" solvents which might cause crazing on sensitive clear styrene.

2-part putties (including 2-part epoxy putty) should not cause crazing.

Within last few years there have been some new water-based putties made available. Those should be plastic safe.

Dr. Microtools? I think it was red.

Wow, we are now going at least over 20 years into the past. I'm pretty sure that was just rebranded Bondo Glazing & Spot Putty. Both smelled and looked (dark red color) the same.

Agreed. That's what I thought, the first time I tried it!
