rev up your engines
Today I'm going to help you answer the question, do windshield repair kits really work, now
realize that windshields are actually made of tempered glass on the outside,
plastic in the middle, and then another layer of tempered glass on the inside, as
you can see, the outer layer is tempered glass, then there is polyvinyl butyral
on the inside, which is a type of plastic, then there's tempered glass on the
inside, now on this crack you can feel the crack on the outside, but you can't feel
the crack on the inside, so only the outer layer is cracked,
now if the glass is cracked on both sides, forget it don't even try fixing it,
because it's gone then, but even so, this crack is so long, there's nothing you can do to
fix this other than replace the windshield, but when you have small
cracks like this one here, you can seal them before the cracks get big and
create a giant mess, the point is, you want to stop a small crack from growing
and then shattering the whole windshield, first you get the pin with the kit, and you
clean out any loose fragments that are in there, then you get the alcohol prep
that comes with and make it nice and clean, then you get the backing plate, put
it over the center of the hole and push it on, then you pull the cover off there, and
put this little cap on, then you get the resin, and squirt some of it into the
hole, then you get the syringe it comes with, plunge it into the hole,
then you pull up the plunger and lock it in place on this low notch, and let it
sit for a while, they say wait about 10 minutes, then you take off the syringe,
that let some air in then you push it back in again, goes into the hole, you twist it and
put it on the second notch, then you wait about 20 minutes for it to seal
itself in, then you take the whole thing off, peel it off, then you put a little dot of the
resin on the hole, and put this curing strip on top, and you want to do this
while the sun is shining, because the ultraviolet rays are what ultimately
cure the resin, but I'm not a patient man, so I use my UV light to cure it much
faster, and now when I run my hand over it, it's smooth it doesn't have the crack
anymore, the trick is to catch it when they're small, if they're big like this
one, forget it, because if they start big like this one, there's no hope at all, the
crack will just grow, especially when you put the defroster on when it's cold in
the winter and the heat gets to it, it will shatter like mad, so now you know about
windshield repair kits, in a pinch with a small crack, they can help you out, just
don't expect miracles, more quick fixes on the Scotty Kilmer Channel,
