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

Good quality, quantity was a little low but the quality was really good

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.

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...

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

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

Beautiful colour.Sandable as promised.Worth a buy

Primer could be used to get a super fine finish for spray painting. It also fills small holes.... It is sandable....

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.

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 coatsThis 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!

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.

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.
