FAQ

01. What surfaces is it best for?

Ideal for:

Automotive finishes (paint, primer, clear coats).

Metal (rust removal, polishing).

Wood (when refinishing with water-based stains).

Plastics & fiberglass (marine or automotive repairs).

02. How do I choose the right grit for my automotive project?

Rough sanding (shaping/removing material): 80–240 grit (e.g., removing old paint, smoothing body filler).

Medium sanding (blending/prepping): 320–600 grit (e.g., feathering edges, preparing primer for paint).

Fine sanding (finishing): 800–2000+ grit (e.g., wet sanding clear coats for a glass-like finish).
Start with a lower grit for heavy material removal, then gradually increase grit for finer finishes.

03. What is auto waterproof sandpaper, and how is it different from regular sandpaper?

Waterproof sandpaper is designed for use with water or lubricants during sanding. Unlike standard sandpaper, its abrasive grains are bonded with water-resistant materials (e.g., resin), and the backing is durable enough to withstand moisture.
