    Don't know what I was thinking... sprayed a black sealer coat for a red topcoat. I know I should have gone grey, red, or white. So what will the effect of the black under red be? If it will make it darker should the topcoat be made a little light to offset this? Thanks in advance.

  2. Try a spray out card and see.
    I bet it's darker.

    ask the supplier what the SS code for the primer for the color you choose is. if the paint isn't bought or sprayed yet, you have done no harm. just by the correct color sealer paint and use it as the first coat before spraying paint.

    Solid red or metallic? Solid might be okay, metallic will likely be darker.
    Test spray as said above

    Black under red is an old 'trick'. Mostly done with paint (on body metal) it is sometimes done in other places.

    My son has a '27 Track T, interior was tan, (Ugh!) he dyed it black, sanded it, and dyed it red. Beautiful 'Oxblood' now, looks like 1940s.

    There's mistakes and there's happy accidents.
    Like the man said; spray out a test card. You may have a winner anyway and love it.

    Darker. Made the same error on a 68 SS Chevelle. I thought the darker sealer would make chips less noticeable under code RR (re-sale red). The car matters because I painted the rear tail light extensions off the car and did not use the dark sealer on them, I used a grey sealer. When I bolted them back on the car, WOW, what a hideous difference it made. I ended up repainted the extensions to match the body.

    That was B/C and Centari if memory serves.

    red paint is a little translucent. it will probably be darker, but you might like it. Shoot some and find out!

    The question is how transparent, if any at all, is the top coat.
    If the color is transparent it will be affected to some degree depending on number of coats.
    If not, spray the color to hiding. Use the checked hiding labels to confirm hiding. Done.
    Lesson learned.

    I don't have the paint yet but it is going to solid, no metallic or anything else. My nephew will paint it in his booth and he'll get the paint. I presumed it would be darker. Maybe do the white sealer over the black before actual colour. I don't want to build it up too much though.
  13. Ever seen a spray out card ??
    If your nephew has a booth then he's probably got them.
    Spray the card and see how the sealer color changes the final color.
    They have others with block checkers to test for full paint coverage too.

    Shoot the sealer too early and you'll need to sand it and reshoot it anyways

    Yep, well aware of the coverage/block checker cards. I'll ask if he has some spray out cards. The colour is going to be a beautiful Burgundy similar to a Jag "Regency Red". I just don't want it to come out too dark. Would mixing the paint formula a little lighter counteract the black sealer? Will have to wait for the spray out card. Than,s for all the replies.
  15. That's way above my pay grade.

    I can say for sure that messing with a expensive paint isn't cheap. Custom tint off the hip is an art. You can wind up with a totally different color. I know It's easier to darken than it is to lighten. Seems counterintuitive but making it darker is "subtractive" mixing vs making it lighter is additive mixing. IMG_1128.JPG

    If I'm looking for a nice bright POP I'll use a white sealer. Lots of reds are formulated to be shot over a red sealer so the finished job comes out the as the sample.

    This is a very unorthodox candy job,
    Resulting in "additive mixing" effect. It's pure black no cloudy mica.

    Halogen sun

    I tried way too many damn red bases to get it. Here's just the base cleared.

    I have some more of a motorcycle I did with 2012 Dodge furious fuchsia. Shot a test on white sealer and it was too pink. Shot it on black sealer and it was a fantastic raspberry. Super sharp on a chicks bike. The pics are in the cloud and it won't let me in.

    White sealer = bright pink.

    Painting is a black art of equal parts voodoo, Druid practices, sorcery, and chance! Thanks again for all the replies!
  19. I did the same thing a couple of months back. I fixed some stars in the fenders of our red 32 car and used a dark grey, almost black, primer underneath.

    You can definitely see it, especially in the sun, but you have to look for it. With the curve of the fender and reflections of trees and clouds in the paint no one has ever caught it but I know it’s there.

    Ironically it seems to have gotten better as the paint cured which I thought would be the opposite.

    I’m just gonna let it ride and not worry about it. Just keep going and see what happens. You may be OK. Not perfect but close enough.

    to achieve the color, the formula was made to, some/most paints require the correct shade primer. reds usually don't cover well.
    i did a british racing green paint that i sprayed over a gray primer. 5 coats and the color never looked right, that is when i learned about the ss codes for paint. used ss7, which was black and what the color called for and the color was perfect on the first coat. no voodoo.............
  21. That's how I feel about metal finishing. Lol
  22. Ever get this one ,,,

    Hey! How did you do that? Magic??

    Oh no, I just read the directions.

    Anytime I have done gray / black primer spray outs 90% of the time the color does change but only noticeable when compared

    I had a problem with cheaper alternatives like Omni not having good coverage on top of a gray primer it was almost like candy I had to keep adding coats till the fender blended rest of car

    they use a the ss codes to denote the color of the primer. ss1 is white, ss7 is black. there are greys and reds in between and formulas for mixing them to get the desired shade. the can of grey posted, tells me it is a very light grey. 91pS60uD0OL._SY450_.jpg Unknown.jpeg
