DEAR COSPLAYERS & 3D PRINTERS. everyone has heard of using rustoleum for props and 3d prints, but is it actually worth it? I can say 100% yes. fills gaps, dries quick, easily sandable, and affordable…but you have to know HOW to use it, so here’s some tips from someone who’s used this primer a lot! (picture is credentials for my info) - run it under warm water for a few minutes before spraying for even smooth coating. this is especially important in the winter. - do not be afraid to apply a THICK coat, you will end up sanding it all down. save yourself the hassle and don’t worry about perfection or drip lines -do not use rustoleum to fill in large crevices or gaps, this product is for thin lines and bumps! - wet sand with a medium grit in circular motions! my process is bondo>sand>rustoleum>sand>rustoleum>sand>paint. I get perfect results from this, but you can always just do one layer if you don’t need perfection.

GREAT! Good price too!

I used this based on recommendations online to help get rid of layer lines on 3D prints. Overall it does does, but it requires sanding before and in between each coat. It also leaves a dust residue that needs to be cleaned up and gets everywhere. I realize it isn't intended for 3D printing, but with some patience you can smooth out ever the most dramatic layer lines on curvature and end up with a final product worth painting

Good quality

My go to primer. I spray guitar bodies with this even if I use an all in one paint, never had an issue. Never had a run with this primer, it sands smooth fast and easy, and sticks with very little prep.

Great for auto body work

Sprays evenly and fills small imperfections pretty well. Sands nicely after drying and worked great for prep before paint. Good coverage, but make sure to apply light coats to avoid runs.

Don't think much it's an excellent product just buy it

Best primer I've ever used. Almost wish there was a spray paint that worked just as well. Really even coating application, dries quickly and fills even better! Was able to use one can to generously coat four 20" wheels and easily filled the road rash on all rims.

Perfecto para el postprocesado de impresiones 3D. Permite ocultar las líneas de la impresión y después de una lijada con lija de 400 o más fina, deja una superficie lisa. Puedes dar varias pasadas y deja la superficie lista para el pintado. Yo lo he utilizado con pintura vinílica o con laca en aerosol. Con ambas funciona bien.

I’ve been using Rust-Oleum Automotive 260510 12-Ounce primer spray to coat 3D printed models (mostly PLA) in preparation for fine sanding and painting. So far, I’m very happy with the results. It applies smoothly and evenly when you follow a few key tips: - Keep the can about 30 cm (12 inches) away from the model - Apply several thin coats instead of one heavy layer - Allow proper drying time between coats This approach prevents drips, runs, or pooling, and makes subsequent sanding much easier and more effective. The primer adheres well to PLA, provides a solid base for paint, and doesn’t seem to react negatively with the material. I may update this review later after more long-term use and painting, but at this point everything is performing exactly as hoped. Highly recommended for anyone priming 3D prints. 5 stars!
