The Value of a Spray Out Card

January 18, 2009—I converted recently to PPG’s Envirobase HP and all seems to be going very well with the product. The colors are mostly good but there is the odd color that needs to be tinted. I need to do spray out cards on all colors and check for a good color match. This also creates a color library and saves time tinting down the road when a color is not acceptable. Proper documentation is a must when tinting a color. I include everything I have done to the color so the next car I spray the same color, the color match is perfect. There are many popular colors out for 2008–2009 so doing a card is a must. I have seen my silver library grow and grow over the last month. I also have a lot of reds and blues which seem to be popular also.

One important piece of information that needs to be added to the back of the spray out card is how many coats of paint you apply. Three is usually sufficient plus the control coat but some colors are low hiders so writing down this info is vital. I also write down what kind of clear coat I use over the Envirobase as we use two different types of clear. I do not seal the spray out card to test if the color covers well or not. This info is documented and kept on file for use at a later date.
It is very important to get regular updates for your computer system as PPG is always updating their colors so ask your distributor for the CD if you have not received an update in the last six months or so. Another great tool is PPG online color library. These are the latest color formulas and variances. If your chips do not provide a close match then check the online color library to see if there are any more variances for your color you are about to spray. Chances are there will be at least one or more variances for you too choose from. So check your color using a spray out card and make sure you add it to your color library for later reference.

Waterborne Not New to PPG

April 18, 2008—PPG has set the benchmark in refinish color match technology with the Envirobase HP waterborne paint system. Why is this?
PPG’s global waterborne platform team shared a primary focus, advancing color match to meet or exceed is most discerning customers. Color experts in PPG labs in Europe and the U.S. worked in close contact with car manufactures and pigment suppliers to create precise OEM matches of some 19,000 prime color formulas dating as far back as 1986 as well as variant formulas from 1996.
PPG has, in my opinion, the best waterborne paint system on the market today.  I have personally sprayed the new Envirobase from PPG and it is not only faster than solvent but has a better color match since approximately 70% of OEM colors are waterborne. This is why trying to match solvent to existing factory waterborne paint can be a nightmare. We now can match waterborne with waterborne and leave the stress and headaches behind us forever. One last thing I need to mention is all PPG color decks are manually sprayed by a human and what you see on the color chips is what you get on a spray out card. You will no longer need to do a spray out card to see if your manually sprayed card matches those dyed color chips those other paint companies supply you. With PPG’s Envirobase you just look at the color chip, if it matches the vehicle you go ahead and spray the vehicle, no wasted time and material.

Estimate refinish times will not change

September 12, 2008—I came across a great article talking about how the two major estimating programs will use the same refinish times for waterborne base coat as they used for solvent base coat. Apparently both companies have done independent studies on waterborne and have concluded the times will remain the same. For me as a painter this will increase my productivity... Mitchell International has performed studies comparing the two systems. Mitchell has studied the effects of waterborne paint systems vs. solvent borne paint and concluded that our current published labor times were in line with the actual time spent performing the required tasks for refinish with either system. Audatex reports that its refinish times are suitable for either refinish method. Rick Tuuri, an Audatex executive says “Audatex around the world and specifically in North America has sufficient data to provide assurance that the refinish times in the estimating system apply to both waterborne and solvent-based refinish systems.”

In the booth, the more air flow used, the faster it will dry. I use a hand held Iwata air blower for one or two panel repairs and I use two blowers on a tree stand for larger refinish jobs. Proper heat and sufficient air flow lets me not leave the paint booth between coats of base. So the moral of the story for the flat rate painter is waterborne is faster so more money goes into your pocket.
