How to Hydro Drip Almost Anything

I was helping my son cut out his pinewood derby car and he saw me experimenting with some painting techniques and wanted to try it out on his car. While this tutorial is based on a car, the subject matter is not critical as this technique can be applied to most objects. As long as spray paint will stick, you can dip your object to create a unique marbleized affect. The first slide is a video showing my project from start to finish. I also created some screen shots of the steps with a description of what you need to do at each step. It is really hard to mess this up so I hope that you have fun experimenting with colors and patterns with your project.

PRO TIP- please experiment on a scrap piece before dipping anything expensive for the first time.

Full video of our hydro dipped pinewood derby car

We created a video of our entire process. Listed below are screenshots of the steps we took to hydro dip his car.

Pick out the paints

For our project, my son picked out some of his favorite colors for his car.

Spray a few colors in the water

Do not spray TOO much because the paint will get thick and leave a texture on the object unless that is what you are intending. Less is more in this case.

OPTIONAL: Stir to create new patterns

My son did not like the patterns that emerged from just spraying so we used a stick to create some new patterns.

Dip your piece when ready

I do suggest watching our video for this one. You need to start with one side and roll it over to the other side to get a good coating.

Remove the dipped piece

I used the stick to collect the paint so it did not DOUBLE dip on the car to create an additional layer of paint.

Let dry

Once it was dry I go a thumbs up from my son. It was ready to race!

    Been doing this for years. Spray paint, nail polish. I have even dipped art canvas panels. I also do acrylic pours

      I do like the art canvas ideas. Never tried nail polish but will have to experiment with that.
