PPG people - paint purchase

[67rstbkt]

So I've painted a few cars myself in the past and decided to paint my current project, but want to take it to the next level as far as quality of product. I've decided to get all my panels down to metal and start with PPG Epoxy, followed by primer. I've used PPG, Dupont, and Omni in the past and liked working with PPG (Omni) the best.

My question is about specific products:

I would like to start with PPG DP50LF (epoxy primer) followed up by Prima K36 (primer, sandable)

For the base I would like to use PPG Deltron, not sure on the clear

Can anyone confirm that the epoxy and primer will work well together? Any suggestions on the clear to use. Any useful tips for me?

Thanks

anyone? I'm probably going to buy the DP50LF tommorrow

The PPG primers you've chosen work great together. Great products in my opinion. The DP epoxy has good anti-corrosion properties. I love the way k36 sands and the fact that it doesn't shrink or swell a year later.

P-sheets, They are instructions for Paint, Product information, You should be able to get them from your paint jobber. I think the primer you may want to look at is k48 instead of k36. Higher build may sand a little easier. Read the p-sheet it will tell you what you can put on top of dp epoxy. It will tell you how to mix it and it will tell you what temp and how long between coats and how long before you top coat it with a urethane primer (k36/48). If you use 401/402 hardener one of them has a induction time. You mix the primer than let it sit for 30 minutes before you spray it. Double check I can't remember what one. It will say on the p-sheet. You also should check what it recommends for a fluid tip on your gun. The have a high gloss clear that I would recommend for overall paint job. I can't remember the number it's been a while. Good luck

Thanks for the replies so far, very much appreciated. I do and will read the P-sheets, just trying to narrow down to the best options - there are so many different ways to do this....

Your fine with everything you listed, but dont waste on that good material by putting Omni over the top of it. It has very little solids, and will take 2-3 times as much to cover depending on color. Use Deltron and 2021 clear.

Yep, planning on that. I just meant that I've used Omni in the past, will not on this one. I will be using Deltron for base and was looking for input on the clear as well as primer layers. Looks like the 2021 is the way to go?

I think the clear Travis mentioned might be the Concept 2021.

yup, Deltron all the way. VERY happy with that line. You're on the right track.

What color(s) you doing?

I'm going with that Subaru WRX color - WR Rally Blue I believe

I went and picked up the Epoxy and Primer at my local supplier, they did not have any K36 or K38.
I ended up getting a gallon of DP50LF and one gallon of DPS3055. I have the sheets for both and they are compatible. I can reduce the DPS3055 to use as a primer surface or spray with just activator to use as a filler.

My plan is to use the Epoxy first, then follow up with the DPS3055 reduced down a bit, followed by block sanding before the base and clear

Only the old timers here will remember this one. It is subaru blue

I've searched all over and was never able to find a first gen in this color; that looks awesome! Thanks for posting that pic!

I used PPG DP/50-K38-Deltron Base and 2021 clear. Worked great. the one thing I would be VERY careful with is the base and clear reducers. Particularly here in FL, we use the hot weather reducers more than other parts of the country. The PPG reducers are VERY aggressive. Despite the fact that the higher temp reducers may lay down more flat, i would go a step cooler in reducer if you have a choice. If you are worried about orange peel, turn your air pressure up some. The reducers can lift areas in the base (stripes, etc.) if too warm temperature. I hope that makes sense, this was the first car i have painted in 20 years...

Too eliminate those issues add DX57 hardener to the base coat. All those problems go away. Plus by using it you aid in adhesion and chip resistance.

DP is a great epoxy. Take you time between coats, let the parts flash nicely. Wait several days before applying the DPS primer surfacer. DP takes 7 days for full cure. The longer you wait the better.
The DPS can spray 4:1 as a filler primer, but I spray it 4:1:.5 using a little reducer to help it lay down a little better, less chunky.

As far as the reducer discussion, a good rule of thumb to live by is to use one temp range higher than the ambient temp. Going colder isn't horrible with primers etc, but in the sealer, base and clear you will affect how the products lay down and the overall look of the paint job.

If you have any questions just ask.

Hope your project is going well, I am a PPG certified instructor and have been in the collision industry for about twenty five years. Your material choices are great, the DPS is a newer primer with great filing and sanding qualities. On the DP you should use the 401 catalyst, I like to let it incubate for at least thirty minutes and usually stir the mixed product several times so you get a good mix and the catalyst works completely. you can topcoat this primer within the hour if you only apply one coat of it, the "up to five days later" is figured on seventy degrees and fifty percent relative humidity. If you push this time you could risk adhesion, if I let the primer sit overnight and it is warm I will at least sand out the nibs, at the most I will scuff with a new red scotchbrite pad. The P sheet will give you all the info, I would recommend a descant drier for your air supply so you have no moisture problems. I like to use Global D894 clear on restoration jobs, it is a 3-1-1 mix and is very easy to work with, but 2021 will serve you well also. I would also stay with the next stage hotter reducer so you get better leveling and more of the product stays on the car.

Nice! Thanks for all the info! I am taking notes and will definitely apply what I've learned here
