C2 hood weatherstrip glue line

[Tony S.]

Just returned from a great meet at Frisco. There were alot of really great cars there.

One of the issues that usually comes up during chassis judging is the amount of glue applied at the factory when the hood weatherstrip is attached. When the factory applied the glue to the top of the hood, the installer used a 1-1/2" wide brush to brush on the glue. Several cars that I've judged--even at Nationals--exhibit little if any visible yellowish/brown glue on top of the hood. I've attached a photo of a great example of how prominent the glue application was at the factory. This photo was taken at the Frisco Regional of a beautiful survivor '67.

That was just one Corvette. I beleave the person didn't care how much went on & some got a lot & others got very little. Also some colors especially yellow will not show as mutch as other colors.

Yup! When you apply the "correct" Ply-O-Bond brand yellowish-tan colored glue on a red car you can hardly see that it is there. I recently did this on a red car and did not over apply the glue, just enough to show that it is there to get the points.

Re: C2 hood weatherstrip glue line

I Have a question on the glue. does it even warrent any deduct because the glue may not be sloppy as the factory did it? I would be thinking that a dot would be a correct and note about the amount of glue.(It seems so minor) I would be looking at the the weatherstrip configuation and if cut was correct,along with the attachment, condition. Thanks for your input. Ed

Re: C2 hood weatherstrip glue line

At a recent regional where my '64 was judged it was noted that the glue was brush applied and no deduct was taken. As I said I applied just enough so that it could be seen. It is clearly stated in the TGJM that it was sloppily applied so that is the standard they are judging to and are looking for. When I judge I wouldn't take more than one point and note it as NTFP.

Re: C2 hood weatherstrip glue line

I'll have to agree with Ed.
(for 64): There are a total of 3/3 points available. So for originality we have 3 points with Installation being worth 0.6 points (20% of 3). From the JG we only care about the cut off points and if yellow "may extend beyond the edges of the weather strip" So to specifically meet the requirements of the JG one only needs to verify that some yellow appears.

Judges typically have knowledge well beyond the JG. Now its known that GM Production used extra glue, aka from a brush however as pointed out the amount varies from car to car. Some of our factory worker members have even remarked that the glue was not yellow but closer to clear and has turned yellow due to time. Remember the car is judged as arrived at the dealer.

Hope you only got a "dot". Know that I've gotten lots of deducts which do not make sense however the judges are under time constraints so errors will happen.

Thanks Alan.... That's the part that no one seems to understand. It wasn't that color when new. Same for the door w/strip glue.

Good to know.

Re: C2 hood weatherstrip glue line

I'd like to request additional information as to how/why the original poster "knows" that the brushes were
1 1/2" "ALWAYS" - even if you were the "guy" doing it in "19XX" that does NOT mean that it didn't change in other years.

Re: C2 hood weatherstrip glue line

Look at page 135, section 4 of the 1965 JG.

I guess the part of the original post where it stipulated that it was a 1965 was written in invisible ink. Beyond that, you might take notice in the future that "absolutes" in the JGs have a way of biting you in the a__.

Re: C2 hood weatherstrip glue line

I never deduct because it isn't yellow...I deduct because the amount isn't typical. Even someone as blind as me can see a glob like this. I haven't judged all the Bowtie candidates but, the ones I have would indicate this is typical.

Re: C2 hood weatherstrip glue line

Loren; No mention of the size of brush in 64 JG just says "It was affixed with a brush applied amber/yellow appearing adhesive that may extend beyond the edges of the weather strip." That statement has plenty of wiggle room.

For 63/64 the cement was part number 3695016, so a look at other AIMs may show a change in the cement used. That drawing may still exist since it would appear the cement was used for a long period of time.

It's been mentioned that many original cars show some "yellow" and I mentioned the affect of age; so went back to look at old pictures (before aging) however was only able to find a few in Noland's book, black & white.
See pages 30,98,112,197,255,268,369,384,403,415,422 The best is probably page 98

Alan,

The AIMS show GM 3695016 Cement was used for the Hood weatherstrips from 1963-1965. It changed (AIM Revision Record date: 6-17-65) to GM 9981098 for 1966. The weatherstrip glue is missing from the '67 AIM hood page, but is referenced under "Cements & Sealers" (UPC 0-D7) where it shows "9981098 Adhesive - Neoprene Solvent" was used for "Weather Strip To Hood", along with many other parts, including what looks like most of the other weatherstrips.
