KOWA SPOTTING SCOPE STICKY

The rubber coating on my KOWA 821 is starting to get sticky. Is there any cure or remedy to correct this ?
 
I've heard Kowa will refinish it (about $250 back a couple years ago). I've also heard countless alcohol, clenzoil and other things but the sticky usually comes back. I had a sticky issue on another shooting item (not a scope) a long time ago and tried different stuff but the sticky came back after time.
 
I have also heard of KOWA refinishing under warranty. If it was bought from a USA dealer selling US warranty KOWA and not selling over seas product they might warranty it. Some of the EBAY and amazon dealers along with some of the dealers in the back of camera magazines sell product that doesn't have a US warranty. I would give them a call.

I had another brand scope doing the same thing and nothing I tried stopped it. It had come with a package deal I bought for the GearBuggy and the seller disclosed it, I sent the scope down the road to a friend that could really use it. He put some of that stretchy camo sports tape ( that the PRS guys are putting on their scopes to protect them) on it and it works fine.
 
I have a Kowa that did the same thing, paint got soft. Kowa recommended sending it back to the factory in Japan to be repainted.
I took a different approach. I scraped off all the old paint with an x acto knife blade. Used rulers and other straight pieces of metal on large areas, and finished up with the x acto.

I was surprised to find the body is plastic. I assume it is some carbon fiber reinforced polymer. It is a dark grey or black. I never bothered to paint it myself, I just use it as is.

I'd start by dropping a line to the Service Department. I haven't had your issue yet, but for all my other questions Kowa has been great: even when the answer isn't "get a thing from Kowa" they've always pointed me in the right direction.

In the off chance that Kowa can't help you, I had a great experience with Mountain Optics in Oceanside, CA. I needed a definitely-not-in-warranty repair on my 821, and they did a fantastic job for a very reasonable price.
 
I have the same issue with a Kowa 821. Contacted the service department and they are no longer covering the paint under the warranty

Look on Youtube. A guy had this issue with a Jaguar's interior buttons. He went to Walmart (please go elsewhere) and got a bunch of things to clean with. He ended up finding that alcohol worked best.

This seems to be an issue with a lot of rubberized or "soft-touch" items. Eventually they get sticky. My TV remote had this coating on it that felt like a silicone rubber cellphone case. Real silicone rubber cases don't get sticky; the TV remote did. Cleaning with alcohol and then dusting it with something like talc or flour may take care of it. Given a choice, rubberized -anything- is off the table for me.
 
This is down to a poor choice of material. This kind of coating always goes like this. I'm also wary of rubberised finishes now.

I tried alcohol on mine and it kinda worked for about 5 minutes then it was back. I tried everything and nothing worked more than a hour or so. I even tried Talc powder after and again it didn't work. Short of removing it like powderbrake listed above I don't think anything else will work.

This is what i did with mine using rubbing alcohol. Lots of elbow work but got all the coating completely off

Somebody else in another video or posting said that gasoline worked. Alcohol worked for me on a guitar tuner that got sticky.

Send it back to them , mine was knocked over on the firing line on concrete, broke the main housing in three places . They repaired it for free.
 
Some car guys swear by baby wipes on old steering wheels. I don’t know why it works, but they say it does.
I tried those to, its like everything else, it works for a day and then its back, at least on the scopes. I think its because the scopes your dealing with a pair type coating whereas the other items your dealing with degrading plastic material.

They informed me they were no longer covering the paint under the warranty
