Actually not so anymore appearently Reed. Paul H (fragman) has just gotten a glass scratch repair kit and was going to give it a go on his old cube tank. I will see if he can post on the results.
yea I didnt know about it either until Paul told me he had it on order. We will see how it looks. I know his tank was like 20 plus years old and had a ton of scratches on it.
Guys I'm not quit ready to give you a report on the success or failure of this process. I began yesterday and logged 5 hours of polishing to the 30inch cube. Man is it harder than plexiglass. Oh my aching muscles. Anyway I have another fine polishing compound to go before I'll know how it worked. The tru test will be when I put water in it again. Hopefully this week end?
