Thread: PPG's DPLF

Tweet

Anyone else having a problem with PPG's epoxy primer. All of a sudden it has a lower viscosity & does not cover well.

Am I getting some bad paint or what?

Don,
I pretty much quit using DP series since they went to the DPLF (LF=Lead Free). As I used DP under everything I shot.

Its not as good in my oppinion since it went lead free. The viscosity has gotten thinner your right, plus you have to mix the DT series reducer in it now.
It has a tendency to shrink and soak up the top coat, which it didnt do before.
I dont think it holds up as well either.
I switched to using NCS 2004 sealer thats tintable with DCC toners or DCC color , Lays smooth, and covers well.

Might give that product a try Don.

aww man, don't say that! We just bought some for the 65 truck. My 16yo son's going to spray it today or tomorrow. This is his very first attempt at spraying anything. We paid $123 for two quart of dplf and the catalyst. We had planned to leave it primered.

If dplf doesn't hold up well, can we put black blitz over this primer with no problem?

Thanks

SprayTech,

I use DP for the first coat on bare metal & apply bondo over it .NSC is a sealer & I agree a great product ,but not intended for the first coat.
I am disheartened w/DP,but it is all I've used for yrs. & it might still be the best primer out there. I would change to a different product,but do not know of any other epoxy primer you can put bondo over.

Any suggestions?

Don

I will have to check with my jobber tomarrow and see if he likes something different in the PPG line, that body filler can be applied over it .

I sprayed my 37 with DPLF 2 years ago and is alright , but it hasent seen the light of day either , and have not worked on it for a whole year...LOL

Since they took out the lead I think its lost a little of its greatness. Still a good product though.

My son shot the truck just now and it doesn't look bad at all. The flatter it gets as it dries, the better it looks. LoL

The width of the spray ok our elcheapo harbor freight gun was only about 3". I don't know if that was the gun or inexperience on my son's part. He even used a little roll around compressor with no filter or moisture trap. If he gets more serious about auto body & paint we'll spend a little more money on some serious tools.

Man spraying a vehicle with a 3" Spray pattern?
You really need a 6-12" pattern to get good results.
It helps eliminate runs & sags, Plus it lays the recomended Mill thickness.
I wouldnt use it to spray color( unless you can screw out the fan adjustment to get a wider fan pattern), definiately purchase
a good gun( HVLP or LVLP ) for color and clears , your results will be better for sure.
HVLP= High Volume Low Pressure
LVLP= Low Volume Low Pressure
These guns have excellent Paint transfer
meaning: More goes on the vehicle then in the air.

I have a Thread here in the paint area about guns
do a search on my name and look for Paint Guns.
It may be of help for you and your son.

Thanks tech,
I found your post on guns last week and printed it. Great information!

This morning before Judd left for school I ask how wide the fan was and he said he finally got it adjusted to about 6".

Thanks again for the advice.

I think after he drives the 65 to school and sees the reaction it gets it'll really give him more encouragement to get into hotroding. I really think kids need something to keep them occupied. He's playing football on the high school team and really hitting the weights right now. When football is over and done with I think hotroding will be a good, healthy hobby that'll last a life time.

Tech or Don,
Can we put blitz black over the ppg dplf primer?

Dave in WV

Dave, It should be alright.
If your DPLF has cured for 72 hours or more it needs to be sanded lightly before spraying your blitz black or it may peal off later, as DPLF dries hard as a rock .

Good advice.....Don

Thanks,
Can we just use a scotch brite pad?

We really like the looks of the dp primer so far.

Yes.
Don
