I am getting ready to remove and replace the original cracked roof rail weatherstripping on the 64 Impala. Will be using OER part # K430.

When installing the new weatherstrip, is RTV required? I see that the rubber is contoured to fit into the grooves of the metal retaining trim, but should RTV also be used? Not sure what was done at the factory with these. Thanks in advance.

GM used steel clips, glue, nylon T-buttons, channels and screws to hold the w/s depending on the application. If the w/s doesn't seem tight enough in the channel, it won't hurt to put some 3M weatherstrip adhesive on the back side. A look at the body manual will show you if they used any at the factory. I wouldn't recommend RTV silicone in any case.

Hi Bob,

Good call on the 3M weatherstrip adhesive instead of RTV. I should have checked the manual first before posting. Section 14-35 of the 1964 manual nicely breaks down the removal/install.

Just got done redoing all my weatherstripping on my '65 convertible and all looks good now. Went through a bit of w/s adhesive! Some of the w/s fits really snugly into those channels, especially the 1/4 windows. I found that some Windex in the channel makes for a nice temporary lube, or you can use a little silicone lube. Any kind of petroleum-based lube may attack/weaken the rubber. BTW, after experimenting with eBay and other sources, I finally bit the bullet and paid top-dollar for the US-made w/s by Steele Rubber. Top quality stuff and fits like a glove.

I'll try my luck without lube, but may have to give the windex a shot if doesn't go in place easily.

Did you use the yellow or black 3m adhesive?

I used the yellow so it was easier to see against the black and maybe less messy that way, but either will do the job

You need to use 3M weatherstrip adhesive( I use black- you can buy adhesive remover if need to remove extra adhesive ),

The adhesive especially above the door glass and the upper rear 1/4 frames is important to have adhesive . The door glass frames & 1/4 glass frames will pull the weatherstrip out of the stainless roof rail trim without adhesive….

Installation of the weatherstrip should be by a scraper or a screwdriver ( not sharp tools) to push weatherstrip square edges into the same sized square edge on both sides of the roofrail stainless.
It’s easy to miss areas were the weatherstrip in not installed in the stainless edges - so check your work without ripping the weatherstrip.

Do not use windex, - that will lead to weatherstrip not staying in place…
