Primer

[Charles Reese]

Knowing what my project is and being limited to my home garage, my PPG retailer recently suggested I use a new (at least to me) product U-Tech 2K100. 4 parts product to 1 part catalyst and spray. Leaves a very dark and easily sanded (400+) finish … important to me as I am going with dark Rock Moss Green/Black. Have also used this on my pickup bed wood and a light coat on my floorboards.

Product is less expensive (not cheap) than the PPG top line, but seems to doing a nice job for my purpose.

Not trying to stir up a debate on ‘best products’ … just sharing a tip.

Thanks Charles for the Info, looks like a good Primer Finish, I'll have to give it a try.

Charles,

I do like the black primer; have always used black tint to the gray primer to make it black. Nothing worse than a chip on dark color and have light gray primer stick out like a sore thumb.

I saw the last photos you posted, your early pickup is looking great !!!!!!

A source of a quality low cost primer paint is Southern Polyurethane's Paints.

Not saying it is better or worse. SPI has a good reputation.

A experienced body man once told me to never use or open a tube of silicone sealer in the shop, or around the vehicle body or component that is in primer. The vapors prevalent with the silicone cause "fish-eyes". True or not.......I do not know, but it is a practice I try to follow in the shop area.

Keep going......sure will be nice!

I am a PPG user but have also used some UTech products. I would never advise mixing two different brands of product on the same car. Once you get to the stage of needing primer, stick with that brand thru to topcoat.
PPG has a value line called OMNI that is fully compatible with their Deltron line. They also have a Commercial Performance Coatings (CPC) line that is also compatible with their other products. I use alot of CPC EPX series epoxy and CPC AUE-100 single stage for painting equipment and alot of low gloss black on the Model A.
On another car site I am getting PM's from a guy wanting advice on repairing his peeling paint. He used one brand of primer and another brand of topcoat. The paint can be scratched off with his fingernail, no adhesion.
It's no surprise that neither co. will help him out. When I was a jobber tech I had to tell alot of shops NO because I knew they mixed brands causing a failure.
Be careful with dark primers, make sure you use a light guidecoat and have ALOT of additional lighting in the shop so you can see where you sanded. It is harder to see small defects in a dark primer.

Mr. Rude: thanks for the encouragement .. in person, the primer color is much darker (almost a black) than in my photo. I agree, i am using the dark to minimize chips showing as much. Unfortunately, the cool weather will prevent any further prep/painting until spring .. will work on some of the 'small stuff' during the winter.

TechNova: thanks for your info. I questioned my PPG dealer when he suggested the UT brand and he stated that they would back it 100%. Maybe I am naive, but i assumed they would not stock/offer it if it was not compatible with their products. I have had Concept over this for 6+ months, including buffing, etc with no apparent problems (yet). I am aware of the problem with dark color so am using light grey during body work stage and using this darker as my last 'primer' stage.

For chip reduction, on a single stage add flex additive.
On a BC/CC activate the base and use a flex in clear.
CHECK WITH THE PAINT MFG. TO BE SURE THIS IS ACCEPTABLE!
PPG has told me it is OK with DBC base and the Deltron clears.

We have a local jobber that has done the same with UTech, the PPG rep has threatened to pull their distributorship. I have never understood why a jobber would do this, most just don't understand. There is absolutely no advantage to them to do this, except of course, the financial kickbacks to managers we have been hearing about.
They must be backing it as a jobber, not PPG or UTech. Is it labor and materials or only materials warranty? time span?

Some jobbers carry multiple brands, I only by from dedicated PPG jobbers.

We have a PPG lifetime warranty, I have been in shops with 3 different PPG reps, all have stated they would give no warranty to shops that have other brands sitting on the shelf. Doesn't matter it they used it on the car that failed, their is no way to prove they didn't so the warranty is gone.

I am not saying every one will fail, you have merely increased the odss of failure. By what percent? who knows, it's all a gamble. Some hardly ever cause problems, others such as a certain HOK base and PPG clear will almost always fail.
