Not really, they will fix it from outside of your windscreen, so you don't need to re-tint. I done mine without re-tint.
And the price they quote is base on the length of the crack, and they give warranty too, dunno 5 years or half year, can't really remember, have to check back. But not sure whether is it the same shop that TS went. The one I went is located at PJ area, same roll with a well known banana leaf rice restaurant.
