    How would I use touch-up paint/primer?

    I have some scratches and a few paint chips on my car. I've ordered primer, base color coat, and clearcoat 2oz brush bottles from paintscratch.com already.

    What are proper steps to apply everything? I know that I only need to use primer if the scratch gets up to the black metal, and some parts of the scratch actually does.

    From what I know, these are the steps:
    1) Clean the area with any wax remover or dish washing detergent.
    2) Apply primer to the black metal areas
    3) Wait till it dries according to bottle
    4) Sand it even with 1000grit
    5) Apply base color
    6) Wait till it dries
    7) Sand it even again with 1500grit
    8) Apply clearcoat
    9) Sand with 2000grit
    10) Use rubbing compound to clean up any uneven leftover spots
    11) Wait 30 days then apply wax.

    Any other recommendations or anything I should know?

    to MOL!

    Black metal? That's fancy, the metal is on my car is just kinda shiny and, well... metal colored

    Actually there is a pretty good guide on paintscratch. Click on "instructions" in the menu, or "directions" on the front page.

    You are not too far off. But I have some comments to the following points:

    1. I like to always clean the area with something like isopropyl alcohol, or white spirit, or benzine.

    5. Apply several thin coats, to fill up the scratch.

    7. I wouldn't sand the base coat. Especially if it is a metallic base coat, as this will make the color and metallic particles look different.

    10. The rubbing compund is for taking out the sanding marks, and make the area shiny, not so much for making it even, this should be achived with the sanding paper. But maybe you should try using Meguiar's ScratchX instead, as this will be safer. Don't know if it is agressive enough to remove 2000 grit sanding marks though... But if you use a rubbing compound, be very careful on the surrounding paint, as this will quite easily go through the clear... Let's just say I have some experience

    Btw, I like your choice of sanding paper grits better that suggested on paintscratch. Especially finishing with 2000 grit will make it easier to polish the area afterwards.

      Oh, thanks! I'll make sure to use alcholol to strip the wax/grease on it.

      Since all the bottles I ordered are the brush bottle ones, should I pour a tiny bit onto a smaller container and just use a toothpick to apply? Or would it be a better idea to use the brush that it came with, I'm just afraid that it might pick up dirt and contaminate the rest of the paint in the bottle.

      I'll make sure I tape the area to make sure I won't apply compound to surrounding areas.

      I did read through the paintscratch guides, pretty good. I've googled around and it seems as if 1000grit is too abrasive?

      If I have some spots where only touch up paint is needed, is it okay to start from Step 5?

      Well the maybe it's not black metal, but it's just scratched to the black part of the bumper/doors, I'm assuming it's black metal.

      Edited list:

      1) Clean the area with any wax remover or dish washing detergent, alohchol works too.
      2) Apply primer to the black metal areas
      3) Wait till it dries according to bottle
      4) Sand it even with 1000grit
      5) Apply base color, with layers
      6) Wait till it dries
      7) (Removed)
      8) Apply clearcoat
      9) Sand with 2000grit
      10) Use rubbing compound to clean up leftover sanding marks, and use ScratchX to polish the area.
      11) Wait 30 days then apply wax.

          clean the area with prep-sol or alchohol, dont use dish soap, make sure you clean several inches around the scratch.

          fill the scratch with several layers of paint, remaining below the surrounding surface allowing the touch-up to "flash" in between coats.

          do not wetsand the basecoat.

          fill the remainder of the scratch with clear.

          wetsand the clear with 2k or 2500 grit

          polish out the wetsanding scratches

            Okay, thanks, I just recieved all my products in the mail. I also ordered a bottle of acrylic lacquer thinner, but I'm not quite sure what to do with it.

            I don't need to wait for each layer to dry for basecoat and clearcoats right? I can just brush the base color and clearcoats over it.

            I know I have to wetsand w/ 1000grit after primer layer, but I can also use rubbing compound to take out the sand markers too right?

            Edit:

              why are you using primer? if its not down to the metal
              if its just scratches and chips. too much sanding will cause headaches, you dont want to expand your work area.

              just clean it out, fill it with basecoat then clearcoat, then wetsand and polish it out with an abrasive polish.

              you should let each coat dry a few minutes before applying the next coat



              pour a little bit in a medicine cup, use a toothpick to apply it, sometimes if they are deep i use a syringe.


              Lacquer thinner is good if you get Basecoat blobs at the edge of the scratch.

              Over-reducing the paint slightly on the last coat helps the metallics blend a little better, moreso with airbrusing but only if you have metallic paint.

                Some parts are down to the metal, that's why I need to use primer as well.

                So the laquer thinner just helps me remove excess paint blobs are ends and such?
