would you use the same materials and method for a c3 or 68 windshield install as for the 63 swc install?

Or in short, what is the best way to install a 68 windshield??? This seems to elicit more opinions than the best oil to use, LOL's!

thanks!

 

YES...and NO

You 1968 windshield DOES NOT use a gasket....it uses urethane to bond the glass in place. Make sure that you do not PAINT the area where the urethane goes. Meaning that do not prime it...then apply paint and clear. It CAN BE epoxy primed ( but not to thick) or actually ground down to bare steel.....because the process and special primers that glass companies use to prep the surface so the urethane can bond to are often times made to be applied over bare steel....OR...a layer ox epoxy primer. Check with you glass company to make sure you are compliant with their process and chemicals. And if you are doing it yourself...call the company that makes the urethane that you plan on using. THIS IS VERY IMPORTANT and should NOT be taken lightly.

The reason you ARE NOT supposed to prime, paint and clear the area where the urethane goes..is because of shear. The layers can shear from each other in an accident..and has been tested and the industry follows specific guidelines. Do what you want...but you have been told. AND this is why you also do not want to apply numerous layers of epoxy primer. Its thickness can shear.

AS for the products I listed in the post you used. This product (7708) is what I would use on the stainless trim to seal it off against the windshield frame area...so water can not wick under the trim. I pump it in the 'V' of the trim before I install it.

BUT...Both products are awesome to aiding in stopping and sealing up water leaks. I use it in numerous areas...and has been a great time saver when water testing a car.

I also use it extensively under the "t" trim or the trim at the top of the windshield header and corners to stop all water from getting into the top windshield frame area.
