I've seen some behind the scenes photos with people using this black putty to attach rectangular filter to round lens fronts and so on.
Below is a photo of a MoVI rigged onto a car and spotted that there's a guy applying the same putty to attach the black thingie on top of a Anton/Bauer battery.
- What is this putty? Fun-tak? Silly putty? Thinking putty? Play-doh??

How do you use it?
How does it perform in cold or heat?

Some products seem to go back in to the "original" form like dough when others will harden in time and some are also magnetic.
I'd just want to have sticky dough that attaches the filters in special occasions (plus magnets around cameras and cables is not so good idea).


Any comments are welcome!

Could be Sugru, but you would need to cut that stuff off once it's set.

James,

Found a supplier for this Sugru from Finland and going to fill my fridge with this stuff.
Doesn't look professional but sometimes would need to attach a filter to a lens without mattebox - e.g. in MoVI use when weight starts to be a problem and gaffer cannot hold it. Rectangular filters have a bit rough edges so I think this'll stick pretty well after some hours so need to clean it up asap after use.

Thanks for the tip!

Gaffer tape is far better at attaching filters to Mattbox's.

More likely Butyl...  Every prop guy and set dressers secret stick em.

 

Nasty strong stuff,  petroleum based.

I've used Butyl only as a permanent sealant. That's nasty stuff for cameras, it sits like stone and need a crowbar to remove.

Gaffer tape is still the first option for filters but some quick fixes could be done with the Sugru mentioned above.
Downside is the 24-hour curing time and that there are few things like nylon, ptfe and polycarbonate that the Sugru doesn't stick onto.
Need to try that Black Tac as well. Then I have everything I need to have a kindergarten in my flat.

Black tack is Butyl, but packaged for the film business so costs 4x as much for 1/16 the amount. IB
