⚡ Key Takeaways
  • The 119-hole FT77 and adaptive FF78 discs last 3–4× longer than standard automotive discs — the hole pattern is the reason, not marketing.
  • PuroFilm ceramic cuts faster than aluminum oxide at the same grit. If you're still using AO on primer, you're working harder than you need to.
  • Hook & Loop, PSA, and sheet formats covered — works with Festool ETS 150, Mirka DEROS, DeWalt DWAS150, and any standard 6" DA.
  • The BN38 SiC sheets are waterproof and oil-resistant — use them wet on clear coat or dry on bare metal, same disc.
  • FF19 foam pads in 6" and 3" let you finish right after sanding without swapping tools or setups.
  • Everything ships from the US. No 3-week wait, no customs surprise.

Most guys shopping for car sandpaper run into the same problem: they grab whatever's on the shelf, burn through discs in an hour, and wonder why the finish looks uneven. The grit is fine — the abrasive type and hole pattern are the issue. That's what we built this lineup around.

Why the Abrasive Type Actually Matters

Aluminum oxide is fine for wood. On automotive primer and filler, ceramic cuts cleaner, loads less, and lasts longer — especially on a DA running at 6,000–10,000 OPM. The PuroFilm backing keeps the abrasive layer flexible enough to follow panel contours without digging in. That's not a spec sheet claim — it's what you see after the first panel.

From a Customer

"I bought the Purple Film Sanding Discs FT77 and the FlexPro Foam Discs for DIY sanding and polishing at home. Everything works perfectly — the discs and foam pads stick well, cut fast, and the finish is really smooth. Even the small strips are great for tight areas. I feel like a pro doing my own car!"

Frequently Asked Questions

What grit sandpaper should I use for car primer?

For sanding automotive primer, use P80–P120 for heavy material removal, P150–P180 for standard primer leveling, and P220–P320 before topcoat. FastPlus FT77 PuroFilm ceramic discs in these grits cut faster and load less than aluminum oxide on primer surfaces.

Can I use FastPlus sanding discs wet?

The ceramic film discs (FT77, FF78) are designed for dry sanding only. For wet sanding, use the FastPlus BN38 Silicon Carbide 9×11" sheets — waterproof and oil-resistant, rated for wet sanding clear coat, primer, and bare metal.

Are FastPlus discs compatible with Festool ETS 150, Mirka DEROS, and DeWalt DWAS150?

Yes. All FastPlus 6" Hook & Loop discs (FT77, FF78) fit any standard 6" DA sander including the Festool ETS 150, Mirka DEROS, DeWalt DWAS150, and similar orbital sanders with a Velcro backing pad.

What is the difference between the FT77 and FF78 sanding discs?

The FT77 uses a 119-hole pattern with PuroFilm ceramic abrasive — best for primer, filler, and paint sanding. The FF78 uses an adaptive hole pattern with Blue Ceramic, which cuts more aggressively and suits fast stock removal and featheredge work.

What grit for wet sanding clear coat?

Start with P1500–P2000 to level orange peel, then P2500–P3000 before polishing. Use FastPlus BN38 SiC waterproof sheets cut to size with a rubber sanding block and water.

How long do FastPlus automotive discs last vs standard discs?

In FastPlus testing, FT77 and FF78 ceramic discs last 3–4× longer than standard aluminum oxide discs. Ceramic self-sharpens under heat, and the multi-hole pattern reduces loading — the main reason standard discs wear out fast.

PSA vs Hook & Loop — which do I need?

PSA discs stick directly to a smooth backing pad — used for hand sanding blocks or older DA sanders without Velcro. Hook & Loop attach to a Velcro pad and swap easily. Most modern DA sanders use Hook & Loop.

Can I use the sanding rolls and strips with a hand sanding block?

Yes. The PSA rolls (F737, 2-3/4" × 59ft) cut to any length and apply to a flat block. The Velcro multi-hole rolls attach to a Velcro-backed hand block for dust extraction. PuroFilm strips (FT77) in 2-3/4" width fit standard hand blocks directly.
