First, we need to identify the specific type of excavator that you want to change, such as different types of excavator, such as Cat 320D and Cat 336, whose cost will vary.The quality of paint involved in the re-coloration process, the complexity of the process (full or partial colouring), labour costs and the inclusion of design services will affect the final price.In the market, the basic Cat excavator could start with thousands of dollars, while the high-end custom service could be tens of thousands or even higher.In order to obtain precise offers, it is recommended that professional engineering machine coating service providers be contacted for advice and that they provide detailed and accurate quotations based on your personalized needs.It is worth noting that, in the process of remodeling excavators, it is important not only to focus on aesthetic and personal expressions, but also to ensure compliance with relevant national and local regulations, such as the notification procedure for the recoloration of vehicles, in order to avoid unnecessary inconvenience.In summary, there is no fixed answer to the question of how much the Cat excavator would be colored, and the exact price will have to be determined on the basis of a comprehensive factual assessment.
