Re: {Collins} Paint matching



Wow Glen, that is some great information.  Thank you for sharing that .pdf file.  Since I am in Dallas, what store is the big one you refereed to? I have three within a few miles of me but none I would think of as a big store.

Each sample is read and just what amount of each "tint" additive to add to a specific base is determined.  There are no "predetermined" colors.  So far, every item that I have had matched are "spot on".

Also, the exact color something is after several decades of exposure to "the elements" varies considerably depending on a lot of factors including exposure to sunlight, cigarette smoke, ambient temperature, and so forth.  The result is that it is often impossible to come up with a "touch up" paint that matches the exact color that any individual unit now has since the environment in which the cabinet has resided for decades varies that can be used on multiple items.

The color in that area generally is going to be the closest to the original paint color.  But, I generally strip the original paint and then repaint the complete cabinet.  If one is trying to find a "touch up" paint then the exact cabinet that is to be matched has to be individually considered and that "touch up" paint may, or may not, be suitable to use on another cabinet.

There is a larger Sherwin-Williams outlet that is about 10-miles away that supplies paint to the telecommunications industry in very large quantities.  If I need a particular type of paint that my store does not stock, then I do go to this larger outlet.  However, the local store generally can handle my requirements.

They then mix the closest formula, and attempt to tweak it by hand for a close, but often not exact dead-nuts on match.  For example, a military Front panel I will be spraying was a tweaked Ford Gray enamel. (Was hoping for a urethane, but it's still an auto paint so should be tougher than the hardware store stuff).  The end result is a slight bit lighter and does not have quite the greenish tinge as the original lacquer, but is the closest I could hope to get of the suppliers I am aware of.

Where or what paint houses have such systems??  I have a 30S-1 that has turned out to be a much larger project than anticipated, and will be needing to spray the entire cabinet.  Ideally, it would be nice to have available an exact color for front panel touch ups, and countless other radios that weren't built in I-O-way.  Maybe I'm just pickier than most..  But if I'm going to go to the trouble and effort of having paint custom mixed and then go through the proper paces to professionally spray it, I want it to be dead nuts on.
