#Making PLA UV resistant?

We all know PLA is not completely UV resistant. I have a job to make a part from PLA for a car that will be on the outside. Can you make PLA more UV resistant by coating it with primer and spray paint? Also will it hold up better during high temperatures?
I currently can't print PETG (I know that's the best solution)

While it is true that PLA is not completely UV resistant, coating it with primer and spray paint can provide some level of UV protection. However, it may not provide the same level of resistance as printing with a UV-stable filament like PETG.

As for high temperatures, PLA has a relatively low glass transition temperature (around 60-65°C), so it may start to soften or deform under prolonged exposure to high temperatures. Applying a primer and spray paint is unlikely to significantly improve its resistance to high temperatures.

Alternatively, you may consider using a filament specifically designed for outdoor applications or high temperatures, such as ABS or ASA. These filaments typically offer better UV resistance and can handle higher temperatures compared to PLA. However, keep in mind that each material has its own strengths and limitations, so it is essential to choose the one that best suits your specific requirements.
