Got a pair of kappa 6's with opaque/yellow polydomes. Sound good and supple.
Removed from cabinet and took apart ( easy ). Applied 303 aerospace protectant,
$6 for 2oz. At first it left a milky residue but wiped it off with paper towel. This
morning the polydomes look new! I have no idea how this stuff clears the poly's
but it does so nicely.
I have an ebay poly on the way. It is yellow and i plan to treat it with the 303
product also. Will post before and after pix.

303 is a great product and I have used it on my cars for many years but I'm not sure how much good it will do on these old PolyDomes. I did use it on mine after I got my K7's and, while it did clear them up a little i don't think it really helped prolong their life as both of mine split around the edge where the dome attaches to the surround.

I think that once any yellow shows up the material is shot.duh! I cleaned my 6.1ii made 4-25-96 polydomes and they are clear and feel very supple. However the yellowed damaged pair from my 7 kappas although cleared when cleaned could not handle me gluing a dust cap on as it tore where the coil is glued. It seems that the 303 is designed to keep plastics and various rubbers that are in good shape from feeling the direct force of harsh environments. The silicone oil never made since to me as the poly dome is a "poly" figure propylene and silicone would also build up. I heard mention of the tire softener but have had friends that race go carts for years and see those tires as they end up, hard and crumbly. Armor all should be renamed armor ain't. Just make sure you do something as letting sit anywhere as they are they are soon to fail. I think the 303 seems to be a good choice for prolonging our beloved polydomes. Btw I am sending my busted polydomes to millersound shortly. Happy listening my fellow sound junkies!

Hey Grinch, did you ever send your domes in for repair? If so, what do you think?

SSSSSSooooo here is an update on The Polydome Surface Repair Stuff. It's been 9 months since I Applied it and there is no color change. Here is the pictures. This stuff works so far. It's not an oily or greasy product. Once it's dry it will always be dry to the touch. Thank You.

The 2nd polydome pic to the right looks a lot more yellow, is that the before treatment pic?

Water based polymer coating.. Happened to notice when I bought some sealant for the cork on my fishing rods it was the same stuff (a little more watery). Going to dig out an old dome and see what it does. On a piece of plastic it leaves a super thin, yet strong, clear film layer.
6.00 for 2 ounces.

Did you treat both sides or just the outside? Also would be interesting to know if it actually affects flexibility or just makes them look nice.
