Скачать или смотреть The BEST Rattle Can Primer for 3D Prints? | Upol Expert Sandable vs. Rustoleum vs. Other brands

Welcome back to Coz3D! Today we're diving deep into the world of primers for your 3D printed projects. Not all primers are created equal, and in this video, I share my absolute favorite primer that I use on almost every single build: the Upol Expert Sandable Primer (Two Times Coverage).

I compare Upol against other popular rattle can primers, including Rustoleum Automotive Primer and Iron Armor, explaining the pros and cons of each [01:02].

Why Upol is My Top Pick:

High Build Volume (Thickness): The main reason I choose Upol is its thickness, which is key for quickly building a layer to minimize and cover those pesky print lines [03:51], [05:30].

Quick Cure Time: Upol's fast drying time (often ready for a second coat in 5-10 minutes) is crucial for speeding up the finishing process, especially when compared to alternatives like Rustoleum that take longer to cure [03:02].

I also briefly mention the process of using Bondo spot and glazing putty mixed with acetone to handle print lines before priming, which makes the entire process faster [04:41].

If you're looking for a quick-curing, thick, high-quality primer for your next 3D printing project, this is the one I highly recommend!
