Default Install my own weatherstripping?

I've ordered a complete set of weatherstripping for my 79 Corvette. I asked my husband to get a price for installation from the Chev dealer and he looked at me like I'm crazy. He figures there's no sense in paying someone for something we can do ourselves and said "What happens when you paint it, are you going to have them remove and re-install the weatherstripping for you then too?". Good point, but its costing me $1300 for the weatherstripping and I figure if I screw it up its tough luck but if the dealer screws it up I can say "Make it right". I can see that most of the installation is probably pretty straightforward but I'm concerned about the t-roof weatherstripping in particular. I thought I read somewhere that the t-roofs need adjusting after the weatherstripping is changed and if that's the case I wonder if its a good idea to do it ourselves - I want to minimize the possibility of leaks. As it is now water is coming in at the top of the door windows and at midway up the doors at the front and rear of the doors and its making me crazy.

In my opinion replacing the weatherstripping is not a hard job. In my case I replaced all my weatherstripping after I repainted the car. The door seals if you test fit them and mark reference points they will go on straight. My late model 77 T-top seals were very easy because the seals have like teflon pins that keep them aligned when going back together. The rest of the seals are pretty cut to exact lengths,

Are the t-top seals glued in place and if so what kind of glue do you use?

I used the 3M weatherstrip adhesive which is available at local parts stores. The factory used the yellow color but I liked the black color adhesive.

I didn't want to buy reproduction weatherstripping and that's what GM charged for it. Some people on this forum said the reproduction stuff didn't fit as well as the OEM pieces. I was prepared to go as high as $2000, if it'd have been more than that I'd have gone with the reproduction stuff.

On the advice of the body/mechanical shop where my husband works I've been buying all GM parts for my Corvette where available. Given that they're usually triple the price of aftermarket I'm not sure how long I'm going to keep doing that.

the weather stripping is a pretty simple and straight forward job get yourself a tube of 3m weather strip adhesive and have at it as per the t-top there simple to adjust if need be. the lock down are a simple rubber tipped bolt and the tongues into the slots are shimmed remove and or add as need. would strongly suggest have your car painted before starting all this as per after they are glued on specilly in the t-tops which are glued and lil weather strip plugs they might get torn or damaged on re-removal then your bust. note places where the chrome is placed on the t-tops as factory stuffed them with dum-dum and if planning on that removal purchase new chrome for the small front trim as that is pinched onto the glass or carefully mask it off.

Sounds like you are realizing what has been going on for past few decades. Aftermarket parts can just as good or better than OEM parts unless you are looking for NCRS judging. I wouldn't walk into GM stealership on a bet.

Hope all goes well with the weatherstripping but just remember the guy who gets stuck doing it probably wasn't born in the same decade as your car so you might be taking it back a few times. As for leaks I only drive mine on nice days but it would be interesting to hear the results of your endeavor

Thanks for the advice elke. I'm not painting the car for a couple of years and its leaking now so waiting is a problem. My T-tops are glass and not fiberglass so wouldn't need to be painted, would that make it okay to do the weatherstripping now and only remove the non-t-roof weatherstripping when I paint? What is "dum-dum"? I'm not sure its a good idea for me to replace the t-top weatherstripping if they might need adjustment, I wouldn't know how to tell if they need adjustment and how many shims to add or remove and when its "right".

Yes Motorhead, it occurred to me that the guy at the dealership has probably never installed weatherstripping on a 79 but I was thinking he probably will have experience on a number of different cars and that might give him a better idea of what to look out for than I have. I might look around and see if there's a shop that specializes in Corvettes that has some actual experience with a 79.

ok sorry i was going off my my 77 tops wish are colored to the car i also have a set of solar tops that i never use lol cuz i think they look funny on my car but thats another story lol. dum-dum is just small strips of butal tape but if yours are glass not to worry about all that. and the tops will be fine to do the stripping since they can be removed for painting and the top area masked off. and if thats all that is leaking go ahead and go for that i would hold off on the doors unless they got issues too. but good to get that fixxed as it can lead to bigger problems down the road like windsheild frame rot out. just replaced a buddy's top windsheild frame and corners due to leaky tops.

well the tops will be easy to adjust to where they look flush with the rest of the car most likely they will sit a lil high but the weather strippng will compress over time. the shims if any will already be under the tongues. i am in the process of repainting my 77 now and got all the fun weather stripping to do yet lol. but it actually in my opion goes on fast then it comes off lol. didnt you say you hubby was a bodyman/mech or works in a shop he should have no trouble doing this.

No, the t-roofs themselves aren't leaking around the roof except at the door windows and the doors are leaking about midpoint up the doors in the front and back. The driver's door is missing most of the weatherstripping that mounts on the door itself.

My husband is a mechanic and although he has done some bodywork and picked up further knowledge from being around the bodyshop I think he's done very little replacement of weatherstripping.

well all that i can say now is its up to you making the choice lol. your hubby being a mech. shouldnt have no issues weather stripping is not that much of a hard deal. so you can eother have someone install it or tackle ityourselves just always remember one door or top at a time as to have one for reference and it will be done in no time. also with no plans to repaint till further years go ahead and get it all done but keep in mind it could be a bear to get off later. good luck and have fun.

Well, I got my weatherstripping in. It was a little less than the $1300 they'd quoted my husband - $1184.71. He ordered it through his shop so I think for a regular customer the price would have been closer to $1800. The Chev dealer quoted him $225 to install not including clips, screws, glue etc. and that doesn't sound too bad to me. My husband and I wouldn't be able to get around to installing it for another 3 weeks or so and there's no way I want to leave it out in the rain leaking any longer than I have to so its going into the dealer tomorrow to get installed. Here's to crossing my fingers and hoping for an end to the leaks - wish me luck.
