Hey all,

my Robbin’s top adhesive failed on the bottom of the rear window, both inside and outside fabric came loose. I’m not the original purchaser of the top so Robbin’s won’t do anything about it.

I fixed the outer seal using 3M window weld and the multiple tutorials on the forum, but can’t find any advise for doing the inside?

It’s a massive pain to get to, especially being a bigger guy. I’m thinking I’ll close the top completely so that it holds the window in place, apply a bead of window weld to the glass (after taping off the glass first) and then try to lift the canvas up to the glass and press it in place. Then use painters tape in vertical strips to hold the top against the glass? I do have a few of the suction cup clamps but they’re crap and barely hold anything.

Anyone have tips for the inside?

 

FYI for anyone tackling this in the future, the painters tape method worked great!

I did the outside of the glass first and secured it in place with suction cup clamps and some painters tape to help. I had the top opened about 3” to give me some slack and supported the window from the inside with a big work blanket. I let that sit for about 6 hours and then moved to the inside.

For the inside, I did have to buy a cheap children’s medicine syringe that is about 4” long so that I could apply the window weld to the glass on the inside. There just wasn’t enough room for me to get back there with the caulking gun. I just used the caulking gun to fill the syringe with 10ml of window weld which was the exact right amount.

I started by squishing down the work blanket to give myself room to work, but also have it there in case of any spills. I propped up the window on the very outside edges using some plastic blocks I had. It really wasn’t necessary, but I just wanted to get the window in about the right position as when the top is closed.

It was really easy to apply the window weld on the glass using the little syringe. Then I had my son tear off 4” long strips of wide painters tape and I gently lifted the fabric up onto the window weld. Basically putting the whole edge of fabric in place lightly so that there weren’t any bunches in the material. The window weld does a good job of holding the fabric in place for the most part.

once I got it temporarily in place (which I did pretty quickly), I then took a strip of painters tape and applied it to the fabric and then pulled the fabric upwards to pull it tight and apply some pressure on the window weld, and stuck the tape to the window. Started from the center and worked my way outwards, alternating left and right.



It was very hot and humid in the houston heat so this part really was a pain (as evidenced by all the sweat on my wind diffuser) and it was really helpful to have another set of hands, though you could definitely do it on your own.

It worked perfect and I now have a nicely sealed window
