I am worried about painting Palladium Silver

I am restoring a 67 Firebird Convertible. I am in the final stages of blocking it now and want to paint it Palladium Silver. While talking with a friend of mine about it he said silver is very hard to shoot.
I have painted many cars. Most turned out great some had issues but still came out good. The last car I painted was several years ago, a 68 Camaro. I painted it PPG BC/CC Lemans Blue metallic. I came out perfect. No tiger stripe, no blotching or anything.I used a gun I bought in a paint store, Vapor, Made in china. Worked perfect when I painted my Camaro.
My questions are, is silver harder to shoot than other metallic paints? Do I need a better gun than my hplv Vapor gun to shoot this silver? Am I going out too far on the limb, having never painted silver before? I really don’t want to drop another $600 on a gun just to shoot this color!
I will be using, unless I am told on here not to, PPG BC/CC. I have a polyester primer on there for blocking and will shoot a sealer right before BC.
Thanks for any help you can give.
EBWelcome to the site.
Are you somewhere not affected by the low VOC regulations yet? and are you going to use PPGs Deltron then?
As far as silvers being difficult, they can be at times. I would say they are less forgiving than others indeed. There are a lot of inexpensive guns out there so I have no idea about the one you are using. If you are comfortable with it, then try spraying a sample and see if you get the results you want. Having a great finish relies heavily on the applicator, a better gun may help but won’t guarantee perfection.
Lastly, I am a little concerned about your polyester primer. It is a good product, but sealing it then basing over wet on wet like that is a little risky, especially since you are doing an entire car. I would highly recommend spraying the entire car with urethane primer and sanding it before proceeding to topcoat. If it were me, I would want to have a little more film build between my base coat and poly primer (or body filler for that matter). If you apply the urethane primer properly and prep it really well, sealer will not be necessary and may result in a nicer finish.
Thank you for the reply. I don’t know what regulations are in my area. I am out in the country in my shop at my house in a homemade booth.
What I used last time on the Camaro was Deltron 2000 DBC.
Now that I think back on my last paint job I did spray a 2k primer over the polyester primer but then I shot a sealer after that. So I don’t need a sealer if I shoot a 2k primer.My gun is a cheap gun but seemed to work great on the Lemans blue with metallic. Does silver have more metallic in it?
What tip should I use for the silver.I have an old door left over that I am going to prep and paint for practice. I just don’t want to buy $1000 worth of paint and then find out that silver is over my head.

Deltron is a good product, if you can still get it where you are..
2k urethane primer and urethane sealer are basically the same thing. Just that the 2k primer-surfacer is designed to build/fill then be dried and sanded. Primer-sealer is applied wet on wet (no sanding required) and has minimal film build. Sealer is most often used on new panels where there is no repair work, but a good foundation for the topcaot is needed (quicker than applying 2k primer and sanding). Sealer does have a few other uses, but that’s a different topic…
So the short answer is no, you do not need sealer at all if you use 2k urethane primer so long as there are no burn throughs in the primer, and it is prepped fine enough for your base coat (finished in the 500-800 grit range).
Silver doesn’t necessarily have more metallic in it than other metallic colours, it just doesn’t have very much for coloured pigments/toners. Every colour and paint manufacturer is a little different when it comes to mixing the paint. Test your gun out, you may be fine, just be consistent and follow the tech sheet. Fluid tip size can vary, but I would think with Deltron in most guns a 1.3 would be a good starting point.
Thanks,
My last paint job I used 2k primer and wet sanded it with 400 and then applied sealer right before the base coat. I did not sand the sealer, I just let it flash like the tech sheet said to do.
I guess I better check to see if I can get the paint I want before I say what I am using.I am going to get the smallest amount of paint that I can buy to test shoot and if all goes well I will jump off for the rest.
Thanks
EBExperience has taught me that Global BC > DBC > DBU in more ways than one , gun setup ,
proper thinner selection and a controlled consistent application usually yields great results . Always remember painting is an interactive process all about adjustments .I am not sure but I believe that DPLF can be used as a w o w sealer over poly primers.Is DPLF epoxy primer? Are you saying you have used it as a W O W sealer?
yes wow!
