Decide the outcome first:
Before anyone sprays a gun, decide what the car is for. Street paint is built for a car that will be driven. The finish should look clean and consistent, hold up to weather, and be practical to maintain. Show paint is built for a car that will be judged up close. The surface has to be flatter, the gaps tighter, and the prep more demanding. That extra quality does not come from a special can of paint. It comes from more time in the bodywork and more time in the primer stage. If you skip that decision, you either overbuild a daily driver or underbuild a show car.
Thank you for reading this post, don't forget to subscribe!Bodywork is the same starting point:
No matter which finish you choose, the bodywork comes first. It is also the longest part of the job. The goal is simple to say and hard to do: the body has to be smooth. The old shop line is “smooth as glass.” That does not happen in a weekend. On a classic car, it can take hours, weeks, or months of metal work, filling, sanding, checking, and doing it again. This stage matters because paint does not hide poor bodywork. Paint follows the shape underneath it. If the panel has waves, pin dents, or mismatched seams, those problems will still be there after color goes on. Show paint makes them more obvious, not less.
Aftermarket parts still need fitting:
Replacement panels do not automatically fit like factory parts. Even new aftermarket pieces usually need work before they belong on the car. That can mean welding, hammer-and-dolly work, and careful fitting so the panel lines up with the rest of the body. Only after the parts actually fit should the main bodywork begin. If you jump straight to filler and primer on a panel that does not sit right, you are covering a fitment problem instead of fixing it.
Primer comes after the metal is ready:
Once the bodywork is done, primer is next. Primer is not a shortcut around unfinished metal. It levels minor waves and small pin dents after the heavy work is complete. In this process, the bodywork needs to be finished to 180 grit before primer goes on. After the primer is sprayed, it also has to be worked back to 180 grit. That cycle is repeated until the wrinkles and dents are gone. This is where street paint and show paint start to separate in time and cost. Both need a straight body. Show work usually needs more primer coats, more block sanding, and more inspection before anyone moves on to sealer and color.
Shortcuts show up later:
There are faster ways to paint a car. Most of them cut time out of bodywork or primer. That can look acceptable from ten feet away. Up close, or after a season of driving, the waves, sanding marks, and poorly fitted panels start to show. If you are deciding whether to build a classic car, this is the part to understand first. Paint color is the visible layer. Bodywork and prep are the job.
Questions about a build:
I write these articles to help you understand the process before you commit to a classic-car project. If you have questions, email info@utahmusclecars.com.
Think about the outcome you’re looking for. In general, there are two types of paint: the first is street paint, and the second is show paint. If you really get down in the weeds, there are more ways to paint, but all they are are shortcuts.
The outcome of both styles of paint boils down to bodywork and paint prep. I will give some bullet points below.
-
The bodywork is the same no matter what style of paint you choose; it is the longest part of the process. You must get the body absolutely smooth; the saying is “smooth as glass”. It takes hours and weeks and months of hard work.
-
After the body work is done, it’s time for the primer. Primer is to smooth minor waves and pin dents, and it needs to have the body work finished to 180 grit before primer can be sprayed, and after the primer is sprayed it must be finished to 180 grit. It must be resprayed until every wrinkle and dent is gone.
-
Even aftermarket replacement parts need to be worked to make them fit your car and this is a lot of welding and hammer & dolly work; then after that, the main body work can begin.
