    You can buy it at Walmart or any sporting goods store that sells tents....I don't recall the brand I last bought at Walmart.

    Seam sealer. Should be able to find it at most sporting goods stores. Definitely REI. They have a couple different kinds depending on the material, but I think the basic stuff should be fine.

    I have also heard that a liberal dousing of waterproofing spray on the seams may help as well. I think it was actually recommended in my manual with new canvas, after setting the stitching with a couple wet/dry cycles.

    Is the leak at the seam or on the window panel? On my camper the window panels are plain canvas and not the heavy duty stuff everywhere else on the camper, so I have to periodically reapply spray.

    Believe it or not, I have heard of people using Flex Seal for heavy leakage from their pup canvas. They insist that it works great.

    Wouldn't a product like that destroy the "breathability" of the canvas? Or, did you mean the vinyl portions?

    Probably. I was just throwing it out there. If it is just a small area of the seam that is leaking, breathability shouldn't be an issue. I'm not advocating using it on the entire canvas. I was just repeating what I have seen others do to fix their leaks.

    I personally would try to repair it properly (restitch the seam if that is the issue) but sometimes a quick, cheap remedy can have the best result.

    Some misinterpretation on my part. I do remember having to seam seal our brand new tent many years ago. After that occasion, I would set the tent up and seal the seams every year. Just made me realize that I did this with our ntu pup when we purchased it last year. Habit!

    Welcome. What popup do you have (make, model, year _ if you add that to your signature line, it helps the rest of us answer better) and what type of canvas? Most tenting needs to be re-waterproofed from time to time, especially after a cleaning, but the type of product to do that depends on the canvas. Many manufactures recommend 303 products, suitable for the type of canvas.
    For seam sealing, the best product we've used through the years on tents and popup tenting is this:https://www.gearaid.com/collections/care-repair/products/seam-sure-tent-seam-sealer
    The brush top makes it easy to work it into seams. I've found it at REI, Sportsman's Warehouse, sometimes even Walmart. They also make a great zipper conditioner, handy on the window flaps in the popup.

    I did a sewing Awl Repair on a seam on my 1984 StarCraft. I used some clear silicone on each side before I sewed it, and a light top coat as well. I won't mess with it again and called this a final repair. Your mileage may vary

    I see yellowish flakes falling off from seams... Looks like I will have to clean all seams then apply fresh new seam sealer....

    Do you have a photo? Sometimes the flaking on the seam lines is the basting tape used in construction, not seam sealer. The flaking was just beginning on our Cobalt the last season we had it - ugly, but it wasn't the actual seam sealer.
    ETA - flaking may or may not mean that it's time to seam seal. We had to seal horizontal seams, between the Sunbrella and vinyl border a year or so after buying it.
