Colour of epoxy primer
I'm about to order some epoxy primer from spi. Just wondering if the colour of the stuff matters. Just for personal preference? I like black because that's how I always see it done and seems to show inperfections better, but ill probly be painting my car blue and white, will the black get covered fine? it wont show through or anything?

Yes it does matter if you are applying your basecoat color over the epoxy. Some of the newer colors have a lot of toners in them and are kind of transparent, as well is the cheaper lines of base not giving as good of coverage. It really depends on what tints and toners are in your color. Have the person mixing your paint look and see if it tells what shade of sealer to spray and try to at least come close to that. Dupont has valueshade, and ppg, can't remember the name, but they have the same thing. The last car I sprayed I was kicking myself for not using a sealer the right shade. I had light grey primer on most of the car, and the dark green original paint on the rest. It took me alot of time and material till you could not see the white primer areas were lighter. The dbc base normally covers pretty quickly, but the color he picked out didn't. Needless to say on parts I didn't paint yet, I sprayed a darker grey on to get them all one color and closer in shade. less coats, less hassle. Now you are spraying two different colors so I would say use a color to match the color that will be on the majority of the car. Hopefully barry will chime in here since you are going to buy spi.

buy quarts of black and white, you can then mix them to the color you like the best for your base... If it is a solid blue, and white, you should be able to mix those two easily and make a nice light to medium grey that will cover easily..


BTW what type of paint are you planning on using??? PPG, Dupont etc..

to be honest I am going against the rules and I dont have my final paint locked down, this is a really slow and tedious restore, and final paint is off in the future. SPI sells a grey primer, maybe I should go for that? I really dont want to be mixing, because im not spraying the whole car at once (right now). I am goign to be just spraying as I go, a section at a time.

When i am done everything I will scuff the whole car and top it with a full layer of epoxy. Maybe i should work with black for now, and then when I am done everything I will top it with grey?

To answer your question, yes black will show minor imperfections a little better.

If you painting the base over the epoxy than you want either gray or as BK said get white and black and blend your own color of gray.

Other than the colors the epoxy is the same be it white or black only difference is tint.

I plan to epoxy slowly as I repair and remove rust, scuff, bondo, filler primer, then I thought it was a good idea to cover the entire car with another layer of epoxy to seal it in well. Thats where all these problems come into play.

so I think what ill do is get a quart of white and black and use black for now. Do all my bodywork over the black to get everything straight and then top it with a light-med grey for the final base.

should work?
