When it comes to repairing deep scratches or acid-etched graffiti on glass, professionals have traditionally faced a tough choice: spend big on costly replacements or accept less-than-perfect finishes. But thanks to Mirka’s Deros RS600 rotary sander/polisher – together with Mirka’s specialised glass sanding and polishing products – that equation has changed.
When it comes to repairing deep scratches or acid-etched graffiti on glass, professionals have traditionally faced a tough choice: spend big on costly replacements or accept less-than-perfect finishes. But thanks to Mirka’s Deros RS600 rotary sander/polisher – together with Mirka’s specialised glass sanding and polishing products – that equation has changed.
Professionals across industries like automotive, architectural, marine and public transport – are discovering that repairing glass with Mirka’s complete system is faster, more cost-effective, and better for the environment than replacing it.
Just ask Daniel from Yarra Trams.
“Hi, my name is Daniel. I’m a vehicle body maker by trade. I work here at Yarra Trams in collision repair. My experience now includes glazing, with all the new trams coming along. There’s so much glass on the trams, and repairs are a big part of that market.”
The Proven Glass Sanding & Polishing Process
Mirka’s total solution isn’t just about the tool – it’s about a carefully developed step-by-step process that delivers consistent results. Using the Deros RS600 in combination with Abranet SIC NS abrasives, Abralon finishing discs, Polarshine E3 Glass Polishing Compound, and Felt Polishing Pads, professionals can restore even heavily damaged glass.
Briefly, the process involves:
Preparation – Clean the glass thoroughly.
Scratch removal – Start sanding with Abranet SIC NS with the Deros RS600, stepping through the grits as required. Note that the starting grit depends on the depth of the scratches.
Intermediate Finishing – Sand with Abralon and water,stepping through the grits as required, then wipe clean.
Polishing – Use a white felt polishing pad on the RS600 and apply Polarshine E3 compound to polish.
Final clean – Clean the area, exposing the flawless finish.
This sequence ensures that technicians can confidently restore both deep scratches and graffiti-etched glass, instead of replacing it.
From Scepticism to Success
When Daniel and his team first tried the Mirka system, they weren’t sure what to expect.
“It's something I was a little bit sceptical of earlier, not too sure how it was going to work or whether it was just going to be a bit of a gimmick. But once we got involved in it and got used to how the the process has worked, it worked out really, really well.”
Faster Turnaround, Less Downtime
For Yarra Trams, saving time is just as important as saving money. Instead of waiting around for new glass to arrive, the team can get trams back on the tracks quickly.
“We don't have to replace the glass panels as much. So we just have to sand the glass out and then it's a quicker turn around. We don't have to worry about ordering glass and things like that. You just polish it out and off it goes. So less downtime for the fleet, get the trams back in moving to the public.”
Happy Team, Better Results
It wasn’t just Daniel who changed his mind – the whole crew saw the benefits.
“Guys are really happy with it. A bit like me, they were a bit sceptical, but now happy with the way it's coming up.”
And he’s confident this approach could work well beyond trams:
“Sure, if someone's doing this in a similar industry, buses or trains and things like that, it would work definitely if they have the right tools… We're happy with the way they've worked and I'd definitely recommend them for somebody else for sure.”
Why Repair Instead of Replace?
Cut costs – avoid expensive glass replacements.
Save time – no delays waiting for parts or stock.
Reduce waste – give glass a second life instead of sending it to landfill.
