Hello Guys,

I removed the front windshield on my 70 Monte (replace with a new shield) and am wondering about a few things. I hope everything is clear let me know if it isn't.

There was moderate surface rust on one corner (pass side lower) and when I sand it down it will remove some of the metal. The metal is still solid no holes. I am just wondering if I should build it back up or will it not effect the sealing of the glass?

Since I have all the trim out should I sand down to bare metal all the edges surrounding the window? After that I will use a proper primer. I am planning to use a chemical stripper and I heard that if any gets into a rubber area it will be bad. I just want to get my car on the road but if I can make things easier for the future it would be good. A paint/body job isn't in the works til the future (winter maybe).

What type of sealer/calking is used for the cowl area where the seams are? I read that 3M makes something but are there any alternatives?

Thanks in advance,

You're better off coating the channel and surrounding area with Por 15. But, on the areas where the surrounding sheetmetal is painted, specifically the door posts and roof, don't extend the Por coating past the trim. Restrict the Por to the metal beneath the trim. This is because Por 15 does not accept autobody finishes very well, although it is the best rust preventative coating on the market.

The area that's pitted can be built up with a product sold by Por called Por Putty. It's a two part epoxy that sets up like steel, but is still sandable.

Here's their site; www.por15.com (http://www.por15.com)

Thanks Randy,

I was planning to use the POR for sure. I have used it before and I like the results I will use the top coat though because the area will be exposed to UV rays. I was planning on using the putty too but I wasn't sure about it being sandable now I know. Maybe I could use the putty on the seams instead of the calking.

For the seams, go ahead and use the automotive seam sealer sold by 3M. I'm not sure of the part number, but people who've tried using the Por Putty on seams were not pleased with the results. I think it has to do with the pliability of seam sealer that hardened Por Putty does not have.
