A scapper with a brand new shinny blade will do the job with ease !!![/quotethats what im doing now ... just wondered if there was an alternative.. its worth trying different methods to see what the best options are
Andrew I use to do alot of builders cleans with a company I worked for when I was 17 onwards and thats all we used as long as you change the blade the regular as you could scratch the glass. Dont think you can beat it especially when you gotta get mastic off !!! Good luck m8 ... I hate them now as done enough when younger so I advoid lol !!!
