C1 (1960) Door post hole

[Donald H.]

I trying to fix the "easy" fixes for deducts that I got in Bowling Green to get ready for the National in Hampton.

I lost a point for the bolt hole in the edge of the door that is there to attach the door post. After the door post was installed, a glob of dum-dum was used to fill the hole and then it was painted to hide the dum-dum.

One guy (not one of the judges) also said there should be some overspray on the weather strip. That would mean that the weather strip was applied after the dum-dum but before painting the dum-dum. The only picture I have seem that show the area was from the '58-60 Corvette Restoration Handbook', and there is no overspray on the weatherstrip.

Picture attached is of my door edge with the dum-dum applied but no paint yet.

What is correct? I don't want to make it worse, so should there be any oversparay on the weatherstrip.

Thanks,

Don

It makes sense the dum-dum filler was painted after the weathersrtrip was installed, but it's difficult to imagine they had all of the colors in spray guns at the trim line just to paint a few square inches of dum-dum. To me that would be very inefficient.

I would imagine they had different colors of paint in jars from the paint shop and used small brushes to paint the dum-dum. Maybe they did get a little on the weatherstrip though.

However, I never bought a brand new C1 so anything is possible.

Don Look on page 19 of the JG under weatherstrips.

Thanks Jerry, I didn't think to look there. Amazing what you can find in the JG

The reference on Page 19 under Weatherstrips & Cowl Gutters "Body color overspary, from painting the strip caulk plug which fills the access hole from the forward door post attaching bolt may appear on adjacent weatherstrip."

I got a deduct at Bowling Green. The picture attached is what mine look like now after fixing the dum-dum and with paint including overspray on the weatherstrip. I've seen a few pictures now and I think mine will be OK now for Hampton.

Just checked my old album of 58 to 60 original photos, and yes the 2300 mile original paint car has brushed on paint touch up over the filler material and on both the adjacent weather strips that run past it. My have stuck that tidbit in the manual revision in 1991.

Don, You better get some brush marks on that paint now! Remember my post # 2. Maybe I need to buy a lottery ticket. I guessed good!

I have no doubt you are correct, but the TIM&JG uses the word 'overspray'. Probaby a matter of a poor choice of words when the guide was written, but if the judges at Hampton deduct for obvious spray on my car, I feel comfortable in challenging them with how the guide is worded.

I may end up going back with a brush. I'm going to try to check with a couple of guys who had their cars judged at the Texas regionals.

Thanks,

OK Rich, I'm adding the brush marks!!

got confirmation of a car recently at regional judging with obvious brush marks and no judging problem.

thanks,

The AIM does not call for dum dum in the hole, it calls for 3711175 cement. Rope putty (dum dum) was compound 3736295. I could not get paint to stick to the dum dum so I filled the hole with dum dum and then applied a thin layer of epoxy putty over the dum dum. Once the epoxy dried, it was easy to paint and if I need to remove the epoxy, I can pry it off of the soft dum dum. I brushed on paint and received no deduct at TX Regional.

My paint doesn't cover the dum- dum very well either. I'm going to try a fee more
coats.

Re: C1 (1960) Door post hole

I think that it was Mike Ernst or Joe Maulsby who said that the hole was filled with dum-dum to close to the height of the hole and then resin was applied to seal the hole and then painted. Makes sense if future access to the bolt is ever required - easier to remove the resin plug and then the dum-dum rather than filling the whole thing with resin.

Dum-dum first, then resin on top.

Re: C1 (1960) Door post hole

Mike Ernst is correct, I have several "plugs" removed from 57 & 62 cars that were restored. The Dum Dum was inserted in the hole after door post adjustment was done, then about 1/8" of filler was wiped in the hole, finished, then painted body color. Don't remember if I noticed "brush marks" or not. I think the Dum Dum was used to keep the door post bolt from becoming "permanent" when the epoxy dried. Any time the door post was adjusted later the "plug" was popped, Dum Dum removed & bolt could be easily loosened.
