WET SANDPAPER 2500

Wet Sandpaper 2500 - the last step before polishing

In modeling practice, 2500 grit is a finishing grade, not a corrective one. The material removes practically nothing; instead it erases the mark left by the previous, coarser paper and leaves a surface that looks uniform once polished or once a gloss varnish has been laid over it. Sanding under water is practically a condition at this grade: dry, the paper would clog at once and would start to dirty the surface rather than smooth it.

When to reach for it

• After leveling the surface with a coarser paper, as the last mechanical step before polishing.
• On a dried run of varnish, a small hair or a speck of dust in an otherwise finished coat.
• On softening the edge left by a sanded-down decal, so that the outline does not show through the final varnish.
• On evening out the sheen of clear parts that are then polished and varnished.

The difference against coarser grades

Lower grades work on the shape: they level filler, parting lines and sprue remains. 2500 grit deals only with the look of the surface, so bring it in at the very end and never try to make up with it for something that should have been leveled earlier. Work steadily, with a minimum of pressure, wipe the area as you go and check it against the light. Remove the sanding slurry thoroughly before varnishing.

Who it is for

For modelers who take gloss surfaces to a high shine, such as cars, motorcycles, canopies and covers, and for anyone who wants a coat with no visible sanding marks.

Protect your eyes while sanding and work in a ventilated area.
