xsmi Posted December 6, 2009 Share Posted December 6, 2009 I am new to the forum. I have searched but have not found anything. I have a pair of black kg4s from 1991 that are looking a little dull. Anyone have any idea of how to bring them back to life? Quote Link to comment Share on other sites More sharing options...
Groomlakearea51 Posted December 6, 2009 Share Posted December 6, 2009 Welcome to the Forum. They are finished with a black lacquer from the factory . Lacquer can be afected (in a bad way...) by using solvents, waxes, or polishes that contain hydrocarbon compounds. Normally wiping down with a damp cloth is what is recommended. In you case, you may wish to try using a "carnauba" based wax (high end automotive wax, surfboard wax, etc.) and buffing the wax out. Try that out on the bottom of one speaker and see if the results are what you are looking for. Hope that is of some assistance. Quote Link to comment Share on other sites More sharing options...
dougdrake Posted December 7, 2009 Share Posted December 7, 2009 And if the waxing idea doesn't cut it, you could repaint them. I did that to my black Chorus using spray paint and they turned out quite respectable. There is a brand and sheen that is a close match to the original available in a standard spray can - I'd have to search to find it as it's seen several years and I don't remember (plus I've slept since then).

Groomlakearea51 Posted December 11, 2009 Share Posted December 11, 2009 Interestingly, both the Rustoleum and the Krylon equivalent are a very good "quick" method to redo your motor boards. It should be done outdoors, preferably in direct sunlight, and before doing it..... practice, practice, practice to get the hang of making the spray evenly distributed. You are looking for an overall "damp" look, not "wet". Best results is about 12" back and fast passes. It will take two cans to do a Cornwall motor board pair, but the end result, if done right, will look as if they were just done at the factory. The paint in the cans is an alkyd enamel, and binds without issues to the factory lacquer. As with any painting.... the surface preparation is the key..... Unless the surface is evenly sanded, cleaned and prepped with lacquer thinner or mineral spirits, there can and will be "issues". Practice...... alot.....
