Is it worth replacing the rear large-windshield glass on 2007 Prius myself?

So how many generation 2 Prius have you seen with fake back glass pieces? I don't think I've ever seen one personally I don't generally look all the time I look at the front glass 90% of those have been replaced but the back generally not so much is it easy to replace pretty much by the way I find to take windshields and back glasses out is to use a multi-tool with a blade that I buy online that's made to cut through the urethane where the glass is glued in front and rear the blade is about $24 it goes on your multi-tool it's extra long it's kind of like a scraper and you just stick it in between the metal and the urethane and the glass and hit the button and it just undoes the seal between the urethane glass in the metal if you go to the glass shop you'll see the glass shop people use a tool that looks like a sawzall with the blade I'm talking about they make the same blade to go in a multi-tool if you don't want to buy the sawzall looking thing or if you own a sawzall you can get the same blade for the sawzall the solves all is a little more to control then the multi-tool the multi-tool you can operate with one hand the Saw's all not so much then again you got to remember the glass place is cutting out your broken glass so it's already broken they're not trying to save what they're taking out you are the multi-tool is not quite as hard on everything if you can understand that the sawzall. Make some serious vibration when you're cutting the glass out the multi-tool not so much
