PPG is the world's largest supplier of automotive refinish paint PPG bought
Ditzler that was at one time a well-known manufacturer/supplier of auto paint.
Deltron is a high-quality paint line from PPG DCC is one of PPGs highest quality single stage (two part) acrylic urethan paint. Single stage means you achieve a glossy finish with one finla-coat product (rather than using a two-stage finish-coat product, a BC/CC BaseCoat/ClearCoat). All urethane (and epoxy) paints are "two part"
DCC Concept Urethane (there are other excellent products by PPG and other manufacturers)
It is of utmost importance to be sure that any product you use from the bare metal upwards is compatible with all other products, especially with the topcoat.
Here are PPG products that are guaranteed to work with Deltron final coat paints.Two words of warning (in addition to using all-compatible painting product) are
silicone contamination: many rubber lubrications and rubber conditioners, and many paint waxes and conditioners contain the miracle shine ingredient, silicone. Even minute traces of silicone in your paint room, and/or in/near any painted or non-painted surfaces, and/or on any of your painting tools/components will ruin your paint job. Better safe than sorry - do not use silicone-containing products at any time AND clean/wash any surface to be painted multiple times with new, clean, white, cloths (or raw paper towels), using a recommended paint prep/surface cleaner (throw away the cleaing cloths/towels after each wiping).
There are different reasons why different brands, quality, and types of finish paints might be chosen for use on any given vehicle. There is no "one product suits all" solution. I will use DCC on my restorations because I want a single stage paint (as original) that can be buffed to a high gloss, that is hard and long wearing, and which has a known long-term stability in its "color integrity".
Also, if you have looked at the the 47-55 Paint Paint Colors Tech Tip, you will see (at the bottom) that PPG has a vintage paint color matching service that has not yet failed me (even in finding codes for esoteric colors such as Pulsar Gray, Thistle Gray, and Anvil gray).
My restored trucks will eventually be owned by my offspring (many years from now, I hope) and I am interested in having a high probability that the paint finishes will last a long time.
There is an excellent set of
