I am in the process of making a Steelhead Rod from a blank I got from North Fork Composites. It was a new blank that Alex put on sale at $150 in JAN for the over 9 1/2' Steelhead blank.. What I want to talk about is the finish similar to Perma Gloss. It is called CPxta which I bought from Bullard before they closed their business about 2012. I bought several bottles of the CPxta and put it all in one of those mini paint cans nearly filling it all the way up and quickly installing the lid. I got the can of CPXTRA from my rod bench tonight where it has set all the years, shook it to hear the liquid inside the can sloshing around. I had already installed the screw in the side near the bottom of the can before I filled the can all those years ago. Now this finish is a one part moisture setting finish. like Perma gloss. So tonight I am installing something unique to me to Identify my rod in the Butt cap. Well to encapsulate it. I unscrewed the screw partway out thru the large scab of dried finish and the vapor pressure forced the finish out of the can along the screw that was still partially screwed in the can. Worked great after having it in that can at least 10 years and used numerous times. My rod room seldom goes below 60 degrees. So air inside the can was minimal to start with and none is added because the vapor pressure is pushing the finish out of the can so no air/moisture is getting into the can to cause the finish to set. That is a lot of years to keep it usable.

I tried to find a photo of the Perma Gloss Container with no luck. I would like more info about the screw (type, size, length) and how it is attached to the can.
Also I am interested in the procedure of how and when to use the screw.
Anyone have a photo.

Thanks

Get a s screw eye. Use a small nail to punch a hole in the can near the bottom lip. Make sure the hold is a bit smaller than the screw eye so the screw eye can be thread into the hole. This will be a sheet metal type thread, not a machine type thread.

With the screw eye about half way in the hole, pour the PG into the can. You want a can sized to the amount of PG you have so that there is minimal space for air inside the can to begin with. Tap the lid in place.

The PG will seep out a little around the screw eye but will seal itself soon enough. After that, you just remove the screw eye and allow what you want to dribble out into a cup and return the screw eye to the can. It won't leak after that initial bulk pour.

Another fan of CPXtra here.

My response for some reason didn't show, but what I had said, "what Tom said about the hole being small hit the nail on the head". So you make a hole just large enough that the tip of the Sheet metal screw can grab onto it and make it's way into the can when screwed. This make a better seal.

Thanks folks for the explanation and thanks Norman for the photo it brings it all together.
