Hey guys...I am starting to put my car back together after paint and wanted to ask a question. I am using the screw in studs to hold the windshield molding clips in since my new roof skin didnt have the studs welded in. I had the studs screwed in but the shop took them out to paint. My question is this: Did any of you that may have used them or screws put a dab of silicone or anything on the threads when installing? I didnt know if I should or apply some not. All the sheetmetal is new and I dont want to attract any rust issues. I read somewhere not to use alot of silicone in the windshield channel because moisture gets under it. Any advice or experience tips would be appreciated...thanks

Silicone around paint is asking for trouble. A little teflon pipe sealant wouldn't hurt. Or even the non-hardening form-a-gasket.

I used 3M strip caulk (sometimes called dum-dum) which cam be found at auto paint supply houses.

My windshield guy said RTV was ok I didn't like those screws I used trusty old pop rivets... Make sure the clips aren't to low in the chanel or the molding sits to low...

Thanks guys...yeah am checking each clip for position so the trim doesnt sit too deep or high. I dont have the glass in yet so its easy. I just didnt want any water finding its way past the screw in the holes somehow and starting what I did so much work to get rid of..Rust.

Gary, You can use a dab of JB weld or similar epoxy when you install the stud for the final time. It will seal and bond the stud threads to the hole, it is paintable, and it won't cause any of the rust problems related to silicone.

uh, Dave, tell your windshield guy that RTV is silicone.

Thanks..makes sense. I thought RTV was silicone based too but wasnt sure. Thanks for the tip!

gary, i would use window weld product so they wont back out. there is a difference in silicone to rtv however tho. silicone is made to put parts together and hold still. as in rtv it is flexible as in stress on back window to move and still seal and hold in place.

3m strip caulk,or dab of 3m seamsealer would work good.Also get your glass guy to put a black border on the inside of window to hide the urethane bead.good luck Joe.

Bill whats Window weld product?...Seam sealer like mentioned sounds good too. I just dont want water to get in there and kill what I have worked on for 3 years to get rid of ? :)

Joe, Whats a black border? I have the glass already. Is it something they do on installation or do you have to order the glass with it? Thanks

The glass guy does the boarder. Also RTV (Room Temperature Vulcanisation)IS Silicone. If it is silicone based, it is silicone. I would NEVER put Silicone on a Car, unless you are going to tile the interior. LOL !!!!!!!

Gary, as dale said in above post a good glass guy will be able to handle a bordor for you.Most of time there 3/4''-1'' wide and will run the parimeter of glass and this generaly done to shadow the bead of urethane they use to set the glass.I'm building a original 69 z back home and that will get glass set with butyl as that is ''correct'' for restorations. My glass guy back home likes to set the glass and then put on the window chrome and then you get a tighter fit between glass and chrome. let us know how you make out.Joe

Ok Thanks Guys ! It may be a little while till I get the glass installed but I thank you for all the info.
