I've recently purchased the Neewer housing for the Sony a6000. I understand this is a rebranded version of the Meikon housing (cheap! cheap! cheap!). One of the differences between the 2 housings is that the Neewer version does not include o-ring silicon grease. So, I thought, no problem: I'll just go to the hardware store and buy a bit of silicon grease. That'll do the job, right?
Well...subsequent research has revealed that there are different varieties of silicon grease, some of which may damage the o-ring. My question is this: what sort of silicon grease should I use? Where would I get that grease? (Meikon sells a grease, but they oddly do not ship to my zip code--I live in San Francisco, CA, USA.)
Thanks, I appreciate any help you can provide!
