How
To Seal Your Windshield
1.
Warm up the sealant by setting it next to a drop light or mild heat
source. You just want to make the sealant warm, not hot. This makes
it much easier to pump the sealer. You also want to do this in a garage
where it will be at least 65 degrees. This sealer needs to flow to
do its job properly. If it is cold, it just won't flow.
2. The window weld sealant uses a standard caulking gun. Snip the
end of the sealant tube on an angle to an opening of just around 1/8".
Push the tip of the tube into the rubber on the glass side of the
seal and apply the sealant around the inside edge where the glass
and rubber come together. Work the applicator nozzle between the glass
and the rubber. You will get a feel for how much to apply. The more
you put in, the more it squeezes out as the rubber goes back against
the glass.
3. Also apply the sealer all around the outer edge where the rubber
meets the body. You want to pay attention to where the molding clips
are. Make sure you pump the sealer in all around the clip. This is
the cause of a lot of leaks in this area. The sealer needs to be all
around the clip so that you can see it come up and out of the clip
as you squeeze the handle on the caulking gun. You want to use a lot
of sealer on the body side as to fill any gaps around the rubber.
4. Let the vehicle sit for several hours and then go back and re-apply
the sealer in the spots that have sank or settled in. You can see
the low spots where the sealant sank in. Re-apply at all of these
areas.
5. Let the vehicle sit for around 24 hours and then water test it.
Start your water test at the lowest part of the sealed glass and work
up to the top. Have someone watch for leaks on the inside of the car
while you test it. This is the best method for determining where a
leak is.
6. Once you are sure that the window is sealed, re-install the moldings.
7. Clean off any excess sealer with clean-solve or equivalent. Check
with an auto body supply shop for a 3M product or another similar
brand. Always
test your paint in a hidden area before using any cleaning solvent. |
