    Need to remove my windscreen

    Last time I used a thin wire to cut it out but it chewed my dash and paintwork

    Anybody got a better way? what do they use to glue it back in?

    the guy that came to do mine just used an ordinary razor to get it off, and used some black stuff called Polyurethane to glue it back on guy filled in my rust with the stuff too :p

    Celica Windscreen removal - How to?

    I'd like to see some of the tools, mine was a wire on two handles but like Mafix said, just kept breaking.
    Maybe there's a special technique?

    I tried a stanley knife with a locking handle but it's very dangerous and very hard on your hands esp around the dash and the screen still cracked when I tried to lift it.
    I also made a long handle with a stanley blade in the end but it didn't go all the way through the glue. When it did the blades just kept snapping off.

    There is a special windscreen cement which looks similar to silicone but dries hard - is that what the pro's are using?

    Rust holes need to be treated with a rust killer first before applying silicone? From my experience silicone traps the rust inside the metal and makes it rust worse.

    urethane, made by 3m. like 21 dollars a tube.
    and yes rust needs to fixed before applying the glue.

    Windscreen removal Tools

    Found some new tools this week:
    This is what you will need

    [​IMG]

    These are available at the local hardware or from Supercheap Auto (NZ, Oz)

    1) A good quality scraper
    To remove glue etc and also cleans all crap from windows. Good quality because the cheapo's break or the blade keeps slipping and usually stuffs your hands.
    Also very useful for removing stubborn gaskets

    2) L - bladed tool
    $25 @ Supercheap. L shaped blade fits between the screen & frame and cuts as you pull the handle,
    no jerking or the glass cracks. Use repeat strokes to cut further under the glass rather than using force.

    3) Windscreen sealant caulk
    $10 @ Supercheap - waaay cheaper than the tube types!
    Caulk gun will give better flow control than tube types

    4) Heavy duty Stanley knife
    Preferably with a locking blade - careful, I've seen these things take thumbs off!

    5) Cutting wire, multi strand
    Hardware only?, 2m length - attach to 2 wooden handles and use a smooth sawing action to cut through the glue.
    Can be a real pain when the wire snaps and you fly across the room.
    Be careful to remove all surrounding trim and watch your paintwork!

    This pic borrowed from Lone Wolf's page (sorry), these guys are working as a team to cut the screen out using the wire, note the plastic protective strips and one guy keeping the hood lining away from the wire

    [​IMG]

    6) Rust converter
    $20 @ Supercheap. This is the type that turns rust purple and leaves a plastic coating - other clear types are acid based and will continue to eat the metal once covered, AVOID!
    Remove/scrape/sand as much rust as you can and brush this stuff on and leave to dry before using filler or silicone

    This is what you can expect to find underneath, as long as it's treated and sealed properly, shouldn't give any further problems. (Once again shamelessly borrowed from Lone Wolf)

    I've got 3 screens to move, so will keep you updated & make a tut

    It's ok to use the photo's :) that's why they are there for ! To help each other out :).

    Those guys didn't scratch anything ! Very good job done.

    I had the rust removed/repaired by a professional with new metal and no thick fillers.

    Thanks Lone Wolf, yours were the best photo's I could find on the subject.
    I was hoping somebody here worked in this field, I know how to work with windscreen rubbers
    but this "new tech" is new to me.

    2 Alterations
    1) I think those dash protectors are metal, not plastic
    2) The cheap sealant is not for gluing windscreens, it is a sealant only.
    Back to the drawing board

    Well, I cut the first one out today, struggled to find wire
    till I realized that picture hanging wire was almost the same

    The 7 strand type was hopeless, the 16 strand was way better and the 20 strand is too thick.

    The problem with the wire breaking is because the glass edges cut the wire and way worse if
    the glass has jagged edges
    Change the wire at the first sign of fraying or the loose pieces will "eat" at the remaining wire

    Care must be taken not to put too much cement around the edge or to cut away any excess
    around the glass or the beading clips will not be able to grip under the glass

    The tool I bought is hopeless, the blade is too wide to fit between the glass and frame and when
    you do get it going it tries to cut into the glass, making a cracking sound, jerking the handle will
    certainly break the glasss.

    I used one of these tools to remove all my glass, but broke the cable free from the T-handle, never worked as good after trying to repair it myself. This tool was awesome for removing the side windows and back glass from my coupe. I did see on the same tool site the they were using one of those new vibrating multi-tools. I have one of those, so next time that what I'm going to use!!

    Here is the vibrating tool I was talking about, mine was much cheaper from Harbor Frieght!

    That kit looks pretty complete and is probebly more than you need for just one windsheild.

    I don't have any picture's for this but the way we do it is like Kevin was saying the tool that he as said with the two handle's and wire in the centre is right and as to be worked on a saw action and need two people to this and pull slowly the wire will never break
    got to be done with time now when cutting use a piece of card board along the wire as you go that will prevent it from doing any damage to the paint work or dash board to replace it like Mafix said use urethane sealer it's the right thing it dries fast and stay's
    flex able

    I agreed and good advice to get a mate to help and most importantly, take your time............. and a couple of six packs :mrgreen

    After all is said and done, one mistake and you'll crack the screen. Be prepared to buy a new one.


    Fix any rust.

    The T-handled tool is about the easiest for one person and will fit under the front windshield glass. The glass on my Celica was very deep set and had very lttle room between the body and the glass edge, was a real PITA to finally cut it out. Mine cracked in about 6 different places cause I couldn't use my T-handle after the cable broke. I'm using the glass as a template for 3/16" Lexan so just needed it to stay in one piece, I just taped it really good to save it from additional damage.

    thanks for the tips! Greatly appreciated!

    So you guys think that windscreen kit is worth it yes?

    Seems like a pretty complete kit to me, not a bad price either!!

    The last time we put a windsheild in our Nissan racecar, we used high density foam weather strip under the glass, then black RTV around the edges and 5 window tie-down clips (3 roof, 2 lower cowl mounted). This set-up might work OK minus the clips (race class required) if you want an easier install.

    It's not worth it because most of the time the glass will crack anyway.


    Let the pros do it and besides that, put a new screen in anyway................. you tight asses :lol
