the chances are that google will answer this question with their own AI (which obviously steals the answer from other sites and claim as their own), so I'd write content on a broader topic like "car painting"
And notice that I didn't say "write content on a keyword with more search volume", but instead I said "write content on a broader topic" and the best broader topic in your example would be "car painting".
In other words, ignore all keywords and just do some research on the topic of car painting and structure your article in such a way that you can cover EVERYTHING there is to cover on car painting, like for example (these are examples that pop to mind, I didn't do any research on this to see which topics actually exist on car painting, so do your own research):
- manual car painting vs service car painting
- car painting precautions and safety measures
- best brands of car paint
- types of car paint
- car painting tools and equipment
- car painting costs
- etc...
Although, re-reading this list it seems like you should silo it differently because - for example - car painting costs could be a sub-sub-topic of the "manual car painting vs service car painting" sub-topic because you could talk about costs of painting your car for both scenarios : when you paint the car yourself vs when you paint it in a car painting service / shop...
Like I said, do your research on what the topic of "car painting" entails and then figure out the most relevant way in which you can group the sub-topics / keywords that you find on this subject. And you can use the keyword "can you paint a car with spray paint?" as a FAQ at the end of the article and in doing this google might pick this FAQ as a PAA...
By going this route you will have a harder time to rank (and you might possibly need backlinks, too) but - at the same time - it will also be easier to rank, if this makes any sense. What I mean by this is that if you create this huge article (I predict that an article that covers everything there is to cover about car painting will end up being at least 2-3k words long) you're going to outrank everyone if the content of the other websites ranking on google's 1st page is poor and / or if the other websites are weak, but if the other websites are strong and / or have good content then you're going to need authority and backlinks yourself, but if the competition for the topic of "car painting" is so fierce I don't think you'll rank with lesser content anyway, which is why I recommended to cover the broad topic entirely.
