I've used Parafilm M for years to seal paint jars. The stuff is great for making an air tight seal.
I don't know what type of jar DN is in, but Parafilm should be able to seal it.
I've used Iwata's to paint models ( the plastic kind:wink: ) for years. The Eclipse is great for all around use, easy to shoot enamels/laquers/acrylics when properly thinned.
The HP series can be finicky when using some water-based paints.
My advice: get the Eclipse for now, buy the HP-C when funds permit.
Hi ya'll. New guy here, with a tip of my own. ParaFilm M is great stuff. You can use it to mask off the bill, seal bottles of paint, & create painting masks.
I buy it off of ebay. You can also find it at hobby shops.
