ROBOCO LABORATORIES - Markron Primer Sealer 4-Color Pack

Used for two months then put up for two years got all three packs back out and still work fine as described from Makron product works perfectly thinking about buying AGIAN especially with prices from Amazon and other companies.

this sealer is a good product to use if your expect to have your reloads exposed to the elements for extended periods. I'd like to see a better way to apply it than with the toothpicks supplied. the brush in the bottle is to big to use on munitions that you've already loaded and I haven't tried to use it as suggested while loading. Lastly the product shelf life is very poor. I had a couple of bottles unopened new in the container in a climate controlled area after a couple years they are totally unusable just rubbery. I tried to rejuvenate a partial bottle I had open, but thinner and alcohol would not work.

This sealer is fine, not great or awesome. It needs to be thinner and flow easier to work its way into a 4 star review. What I had hoped for was to get a drop on a toothpick and then just touch the valley between primer and case and have it flow in to fill that circle. Set the case upright to dry and move on to the next ... 5 second process. Instead you have to carefully work it around into place usually putting too much on and slopping it where you don't want it to go. It makes me wonder what the factory process and product is as most seem to seal theirs and you know they are not wasting man hours to do this step. If it didn't go bad so fast in the bottle then it would get another star. I also was unable to revive the "old sealer" in the bottle.

You need to get the primer sealer thinner if you're doing bulk.
