Rust-Oleum 260510 Filler and Sandable Primer Spray, 354.88 ml (Grey)

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

This stuff is awesome! I've seen a bunch of videos of people using it on their 3D printed parts to get rid of the layer lines, but I didn't think it would work this well. I put two coats on my RC car project and sanded it with 600-grit sandpaper, and it came out as smooth as marble. I highly recommend this product for 3D printed parts.

Excellent product. Works very well if you’re looking for the smoothest base to get a mirror like paint finish.

Spreads evenly, dries quickly and fills up small scratches and marks. Has a pretty nice coverage too. It takes almost 24 hours to "fully" cure and sand the surface. It simply accumulates on the sandpaper rendering it useless if sanded before fully curing. But when it cures up, it provides an even work surface. The cap tends to clog up. So be sure to flip it and spray out some of it to clear the nozzle after use. Only downside i feel is that its a bit on the expensive side...

Wow nice project premium product I am very happy thanks

Good Filling Primer, fills small gaps and gives smooth finish.

The quality is amazing, can use to remove lite scratches and get a smooth surface. Two coats are recommended.

Rustoleum does not cheap out in quantity of material and stay under pressure for long after first use which cheaper cans often don't. Ok consistency, thickness , stickiness to surface and even spray. Not very good as filler as it's very fine. You need to prepare the surface without scratches. I have used primers from several spray can manufacturers. This one could be cheaper. More stickier would have been better (I am using plastic paint promoter).

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.

The Rust-Oleum 2-in-1 Filler & Sandable Primer (12 oz) is a high-build automotive coating designed to streamline the surface preparation process. This gray primer simultaneously fills minor pits, scratches, and imperfections while providing a tough, rust-inhibitive base that is easy to sand for a perfectly smooth topcoat finish.

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.

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.
