Scratched Your Glass Tank? GlassRenu Scratch Removal (1 Viewer)

[steveb]

Thought I would share this..

I bought a 265 in pristine condition (well had holes drilled in PVC bottom) - but it had NO scratches..

Over the course of time I have somehow managed to put about 8 scratches (mostly in the front panel) Yes I am super clumsy apparently...


Well not to worry...

I purchased this

and this

Before I actually do this I need to practice some.. here is my 1st attempt on old 40g breeder.. it may not be the best example to show clarity as the inside is extremely scratched.. but what I was going for was:

1 - could I remove a scratch that catches a fingernail
2 - can I get all of the swirl marks out
3 - will there be good optical clarity once I am done..

I will practice on this tank a few more times and then I will try on a new 40 breeder to confirm #3..

I put this scratch on the outside panel with a carbide bit that I use to chamfer holes when I drill glass..

ouch that sucks, I scratched my aquarium..


Step 1- Scratch Removal






Step 2 - PrePolish




Getting to a uniform haze in the repair area




Step 3 - Polish..
I forgot take a pic of the polishing pad but basically its a felt pad that you damped with cerium oxide and water...

and here is the sequence for that..






Looks pretty clear to me... Start to finish took be about an hour (that was with intervals to let glass cool down).



IMO removing glass scratches is doable, with the correct tools, process and time..


If you would like to see a video of the process on a glass panel here ya go..

I will post another sequence when I do the NEW 40g breeder...

I am curious to see the results

If this works, it is a good find.

55g - step 1 - scratch removal - Clarity Test

Like I said earlier, the other tank has lots of internal scratches so it was really hard to get a good feel for clarity etc.. So I decided to test on a new tank.. I did the back as this will eventually get painted...

Buckle up...





The new scratch...




Beginning scratch removal..

Step 2 - pre-polish

So here is the tank with the scratch removed... but still a long ways to go..

step 3 - polishing

So this is the polishing step.. got a pic of the pad this time..



its messy...









I placed a light grid inside the tank.. why am I posting this? To show that if you feather the repair appropriately there is no lensing effect.. i.e. distortion








Hope you have enjoyed my demo of the glassrenu scratch removal kit..

Yes you can polish out scratches in glass without distortion.. it does take time - close to 2 hours this time..

I did have to go back one time with pre-polish pad as I had some fine whirls in the glass. I think the polishing step would have eventually removed them but pre-polishing is just a lot faster..

Thats great because removing scratches from glass always seems impossible.

By the way, if you can't afford the makita buffer, go to harbor freight and get the cheaper version with the same power.
