[GFX 50S - Place to send - clean dust under the cover glass]

Can you recommend a place to send my GFX 50S in and ask that they clean dust from under the cover glass?

I have wet cleaned the cover glass with a sensor swab, but still have a spec of dust that is always in the same place.

[Fujifilm X-Pro2 / JJC replacement eyepiece - Adhesive recommendation: Adhesive Sealant Clear RTV Silicone ?]

I am looking for a recommendation for a good adhesive for the Fujifilm X-Pro2 / JJC replacement eyepiece.

I read that the JJC eyepiece is silicone, and a silicone adhesive is required; like:
Permatex Adhesive Sealant Clear RTV Silicone (80050)
https://www.permatex.com/products/adhesives-sealants/sealants/permatex-clear-rtv-silicone-adhesive-sealant/?locale=en_us 

After the original fell off, I bought the JJC EF-XPRO2G Eyecup (deep), which is made of "silicone rubber":http://jjc.cc/index.php/Product/product_info/id/1897

I am glad JJC sent 2 eyecups, because the 1st fell off the first time I used it outdoors.
So my question is whether the Permatex Adhesive Sealant Clear RTV Silicone (80050) is a good choice, or if there is a better product?
