Thread: Need Help With Paint System.....

Tweet

Hi Everyone,

Great Site By The Way!!

New member with old question...

My son and I have a "Father/Son Project" that feels more like the blind leading the blind and I need your help! I am trying to put together a material list/paint/coating system so we can paint his car from the bare metal up. We intend on using PPG products. From what I have read the DPLF Epoxy Primer will go on first and Global DG Single Stage will go on last. What I am having my struggle with is what goes on in the middle.

I have read about PPG K36 & K38 (Acrylic Urethane) and also MX 245 (Polyester Primer). So my question is what is best the "Acrylic" or the "Polyester" primers? Also what is the best "Evercoat" fillers/putties to use over the Epoxy and before the primer?? And any other helpful recommendations you may have.


So far this is the process/PPG products I think we will be going with:

DX 330 Acryli-Clean De-wax/Grease
DX 579 Metal Cleaner
DX 520 Metal Conditioner
DPLF 90 Epoxy Primer; (alternate: SPI Epoxy)
Body Filler: F/E Evercoat "Xtreme and or Gold"
Putties & Finishing Glazes: F/E Evercoat "Polyester Glazing Putty and or Euro-Soft"
Primer PPG K36 or K38
DPLF 90 Epoxy for Sealer
Global DG top coat

I thank you in advance with any help you guys could lend,

Glenn

you can save some money by using spi ( southern polyurathane inc.). it's way more user friendly than ppg and a better product in my opinon. i just did a 57 vette using only epoxy , no 2k primer at all. it has been cleared for 90 days and has 0 die back or shrinkage.

I have to second the use of SPI. I've used DuPont products on most of my hobby projects until an introduction to SPI last summer. The epoxy is s-o-o-o-o much better then the DuPont undercoats. The 2K is very nice as well - I'm not in the same league as Shine to only go with the epoxy as the single prime coat tho the SPI epoxy sands as nicely as the 2K. My top coat will still be DuPont as SPI is still limited in color choices tho they have been reported as great to use.

Evercoat Rage is a more user friendly filler then any other that I have used and seems to be the current user's standard

Thanks Shine & Dave for your input on my question and the SPI products...it is good food for thought. I have revised the "filler and putty" section to Evercoat....now just to choose the correct two for the job.

03/06/07: I calculated (by volume) the cost difference between one gallon of PPG Epoxy w/ two qt. catalyst and one gallon of SPI epoxy w/three qt. catalyst and the cost savings would be app. 72.00 less shipping for the SPI. If I purchased less SPI by the qt. then the cost savings would be more.

PS: I emailed PPG today (03/06/07) and it will be interesting to see how their recommendation stacks up to those of you that have actually used the product! I will post thier reply when I receive it.

Good Afternoon,
My son and I have a "Father/Son" project to paint his car from bare metal. The body is now ready for prep and paint. We have decided to use DPLF Epoxy Primer and Global DG top coat ( paint code color 6405; 111 Champagne Yellow)
My question is what is the VERY BEST Primer/Surfacer to use? I have read about your K36/38 and MX245 Polyester Filler. I plan to use Evercoat (polyester base) for the regular fillers and putties over the epoxy bare metal primer. Please include your phone number with your reply.

I thank you in advance and look forward to your reply.

Best regards,

Glenn & Camden

I would recommend the F/E Eurosoft glazing putty. I have used it for about 15 years, it sticks to any sanded surface, feathers beautifully, and I never had a failure.

I recently tried a new, cheaper, Marson product, and had more shrinkage immediately. I'm back with the F/E now.

Thanks HOTRODPAINT for your help!

Also am I on the right track in thinking there should be two different fillers: one for the bulk of the work and one for the final skim coat/touch-up prior to an epoxy sealer? If so do you have a recommendation for the first stage of filler or do you use the Eurosoft glazing putty for the entire job?

Thanks again and I look forward to your reply,

Glenn

Currently I am trying a new-era filler, Marson Platinum Plus.

It, like many new fillers is "lightweight" and formulated to also work over paint. If you plan to primer, before you bodywork, I would recommend this one. It sands very easily, and will adhere to a sanded acid wash primer, or epoxy primer....however, I would bury it in a 2k primer, since it seems very porous, and could cause shinkage.

My old dependable filler is Marson Whitefill. It is very flexible, but must go over bare metal or fiberglass. I've used this one for 20 years with no failures. I always bury it in 2K primer, also.

I use Marhyde's Ultimate Primer. It is a little less expensive than some, and has served me well for 10 years. I always guide coat and block it, then fill and sand the minor problems with F/E Eurosoft, before sealer and color coats.

Thanks again HOTRODPAINT for your input!!

I had sent an email to PPG Customer Service and just heard back from them. I called them to discuss there email and the rep was able to clear up all my questions. What I basically understood from our conversation was the "K" series acrylic primer and the polyester primers are both equally acceptable over the polyester fillers and DPLF substrates. The difference being the product itself. The polyester is just a "spray-on" filler and can be laid down to form a very thick coating to sand off and level pitted metal and other imperfections..... Our car is not that bad so we will go with the K 36 or K38 primer. As far as the fillers are concerned we will use the Evercoat "Rage" Xtreme or Gold filler with Evercoat Polyester Glazing Putty or Euro-Soft® for the skim coat and small stuff.

Thanks again for all your help and getting us on the right path!!!
