Shoe Goo to repair shutter pinhole? Really?

[peterm1]

I found shoe goo a little too thick except for a single pinhole when a tiny tiny dab could be used. Same for liquid electrical tape. I have used a flexible ink for painting on T shirts or for marbling (floating on a liquid medium to produce a dyed marble effect on fabrics) successfully too. Its thinner and yet opaque - and this is sometimes what you need. It also stays flexible of course. One I like is named Pabeo Marbling Ink.

Shoe Goo is really an adhesive. It's also sold for plumbing repair. Like many of these, it's silicone based and tends to dry to a hard rubber-like consistency. I wouldn't use it.

I've also tried Liquid Electrical Tape and recommend AGAINST using it for camera shutter curtains. Works great in replacing insulation on automotive fires and covering bare wires in headphones.

The one thing that I've used to fill pinholes in shutter curtains is a Crayola-brand marker, which leaves no build-up, dries to a smooth finish and fills only the hole and not the surrounding area.

If you're interested, when I get home this weekend, I'll find out the brand name.

Thanks for the link, icebear. Btw, do you remember the lens in question and the aperture? Ive read some posts indicating it requires > f2.8, but I'm not sure how exact this could be. In my case, I was using Jupiter-8 (50mm f2). The Jupiter-8 does not have aperture detents (click stops), so it was easy when setting the camera down to turn it to max aperture.

Hi crawdiddy,
no I don't remember the aperture that my lens was set as it happened but the effect of burning a hole depends on the energy concentrated in the spot of focus. When you focus on infinity and have direct sun in front of you as I had, it doesn't really make a difference if it's f2 or f4, the energy will be sufficient if you hold the camera steady long enough. I'll check some time for the picture that I shot when it happened. If the focus is close up the spot on the curtain will be unsharp, therefore warming a larger area but not heating up a tiny spot to melt a hole. I guess this is more important than the f-stop.
