OK don't tell me to look in the mirror, I admit I am a dum dum. I am not a young man, and all my life I have heard this term associated with the stuff the factory used around screws, nuts on trim parts etc, to make a waterproff seal. The term surfaced again on here http://www.v8buick.com/showthread.php?t=174200&highlight=dum What do YOU use for this purpose??? I have used 3M strip caulk, and a product called DiversiGum, but would like to hear what everyone else uses. Another similar question. What was the stuff the factory used to put the watershields in place, watershields behind door panels. The stuff from the factory had a piece of thread/string going through it. It also seems to last forever. I recently took the access panel on the tailgate of my 67 Sport Wagon off to work inside the tailgate. It had a watershield with the same stuff holding it in place. It was still soft and sticky from 1967!!! What do you use to replace this??? Thanks, Mike
I always associated 3m strip caulk with the phrase "Dum-Dum". I use strip caulk for all door watershields. Also, it's nice to have a roll of butyl tape around the garage. This is the stuff glass guys use to install windshields. It stays pliable and sticky forever.
Agreed, I have done the same. Have these products in my garage also. Keep the suggestions coming. I did a 67 Camaro convertible. Put new tail lights, with new gaskets. Used strip caulk to "help" the gaskets seal, water in trunk=bad. At a car show in the summer, in the sun, the heat got to the strip caulk and it ran down the pretty red paint under the lights, black streaks=ugly. No harm, easy cleanup after getting home.
I put that stuff on every nut back of every clip and script when I was putting all the chrome/stainless back on my Cat. Haven't had a drip yet, especially in the trunk (I had the entire trunk coated with about 1/8" of Vortex Bedliner).
Dum-Dum is a clay like putty used to seal A/C ducts. It is available at Home Depot, Lowe's and Electrical supply and HVAC shops. It works just like clay, pull a piece off, roll it into a ball and press/smear it around what you want to cover.
I know what we all use it for. My question is, what PRODUCT do you buy and use? I want to know what it is, in your garage.
OK, I hear you. But walking into Lowes and asking for dumdum is going to get me nothing, just a clerk saying "I have no idea what you are talking about" What is the name of the stuff you buy, if there are more than one items list them all please. What you are saying sounds like what I get at a HVAC supply house called DiversaGum, I listed it in my original post. I am curious to find what everyone uses, the name, and how I can find it where I live, Thanks.
3M caulking strips. They are about 1 foot in length. I got mine at the automotive paint supplier. Went in and asked them if they had "Dum-dum" and he knew exactly what I was talking about. It ran about $20 for a box.
X2 on the 3M strip caulk. I keep it next to the monkey snot (3M weatherstrip adhesive) I havent found a supplier for the kind with the string though
I know what he means about the original having a string in it. All orignals I have taken aprt had it as well. None of the 3M stuff does. I do not think it really matters. Another tough item to find is the waterproof type masking tape they used on the door paper shields as well.
Good point! What the hell was I thinkin'. ou: BTW - I just saw some Dum dums at a store today offered to make the kids shut up so mom could buy window blinds.
I use black 3M duct tape. Looks almost perfect. I use it on top of the AM/FM radios to mimick the original black tape thats long gone.
