AeroGloss 4 ounce jar lids

Or maybe you could get some empty (new) paint cans from a hardware store and transfer the dope in them?

Gentlemen,

I appreciate your suggestions and creativity!

Cork tends to fall apart, and will eventually contaminate bottles of dope.
Neoprene may fall apart due to chemical incompatibilities...I don't know this, just assumed.

Local paint shop can provide pint and quart cans. I HAD a pint of clear. As the clear gave way to unfilled volume, the remaining dope congealed into an unusable putty. Four ounce bottles can be used fast enough to minimize waste.

Still looking for the size and source of our two favorite dope vendors' bottles (Brodak and Sig).

Keep 'em coming guys!

FWIW, it appears the lid size is 48/400. I'm going to search for this size next.

A guy on StuntHanger suggested HDPE.

1 gallon milk jugs are HDPE. I cut gaskets out of the flattest portions, which yielded about 10 pieces. The first lid had that satisfying smoosh to it as I twisted the lid in place.

Testing will begin on a bottle of thinner to see if it evaporates in the sun. If no loss of thinner, then more will be made to replace my most damaged lids.

FWIW...Sig MFG (SigPlanes said to call the plant) said they will email an offer for 24 lids (a number I said I needed). Brodak said they don't carry that size anymore.

Roddie,
I made a.paint shaker from an old drill. It oscillates the bottoms more than the tops, and has successfully shaken the pigment back into suspension in several really old bottles.
You'll be surprised just how much old dope can be revived!

I guess it is time to figure out YouTube. A picture is worth 1000 Words. A movie is worth 1000 pictures. I guess that makes a movie worth a million words?
