67 Heater box & fan motor
The last Top Flight judging under #17 "Heating or Air Conditioning/Heater box & fan Motor or block-off plate" I received a deduction that says "S/B sealant". I'm assuming the sealant deduction is the "spray on heavy rubbery sealant" referred to in the judging guide. My problem is I'm having a hard time locating this product or I'm searching incorrectly. Anyone able to steer me in the right direction? As usual thank you in advance for your help.

Don,
Interesting. Never crossed my mind. I will take a look at it. Have you had any experience using this product for the same application? Thank you for your input.Comment

No sir,
I have not used it, but I have heard of guys using it, and from my observations of it, I believe that it closely matches the original sealant that was used in St. Lou. The real sealant I have on my 64 looks like old hardened Henry's.

Re: 67 Heater box & fan motor
Was there a point deduction or just a comment? If point(s) how many? Just curious.Comment

Re: 67 Heater box & fan motor
Don,
About 5 years ago Jerry Fuccillo suggested a similar roofing product to re-secure the C2 underhood bracing to the hood skin. Maybe Jerry will chime in to tell us if what he recommended would work for the heater box as well. Does anyone know if both the heater box goop and the hood brace goop should rock harden or remain slightly soft to a thumb nail?

Flex Seal works very well. Home Depot has it also http://www.ebay.com/itm/like/131419234572
you need some that is a little more liquid than the henrys caulk. I have used the fibered roof cement from Henry's as well. it needs to run down in a few places on the box like it did at the factory
the flex seal works greatDan Young

Re: 67 Heater box & fan motor
You were deducted in error. There is no requirement for the heater box to have sealant. Verified by:
"The gooey, runny black stuff was a water-test repair sealant that was used in repair and intermittently on the main line; it wasn't part of the normal heater blower case installation." John Hinckley
NCRS judging should be knowledgeable on this fact that only cars that leaked and failed got the gooey stuff.Comment

Re: 67 Heater box & fan motor
I went back to the TJG 5th Edition on page 157 it states this. "Frequently, a spray-on heavy rubbery sealant is seen along the top and sides and quite often will run down on the front of the face of the heater box. This is a factory procedure and should be considered typical." My understanding and as discussed above, the sealant should not harden. It should remain flexible such as some type of rope caulk or caulk strips which I know 3M makes and I'm sure there are other manufacturers. My heater box was sealed in this manner and I lost points. All it says on the judging sheet is "S/B" sealant. I understood this to mean the rope type looking sealant is wrong. Although from memory most heater boxes in cars from that era are sealed in this manner. However, it's the reference to the spray-on rubbery sealant that confuses me and it circles back around to my original question. Spray-on rubbery sealan.Comment

Re: 67 Heater box & fan motor
Viewing Don's picture of his heater box, mine looked similar except it didn't have the runs. Although the TJG states runs can be present but not always present. My 63 looks like Don's and my 67. Well with all of this being said, it's going back together the way it came apart with rubbery sealant.Comment
