Eastwood Seam Sealer Cartridge Black is rated 4.6667 out of 5 by 18.
Rated 5 out of 5 by from Seam Sealer for that OEM look. I have used several tubes of this sealer so far, matching the OEM sealer applications. I ground out the original hard and dry sealers all over our project 67 Caddy. Pumped in beads (no more then 12" at a time) and fingered them down to match the original where applicable. Removed the original material between the inner and hood stiffeners and the skin and pumped it in the center holes just like the factory and it went in and came out the surrounding four holes just like the OEM process. The hood is now firm and quite, no tinny sounds when you tap on it and no swelling or bulges. Works perfectly, looks correct, sticks well and has the right firmness vs flex. Excellent product.

Rated 2 out of 5 by from Disappointed in Seam Sealer Unlike 3M seam sealer, this product went on very stringy and did not flow into/onto the seams. Used a small brush to help level the material and had hoped the seam sealer would level out smoothly and it did not. Will not use this product again. Although the 3M seld-leveling seam sealer is more expensive it would be well worth the extra money to invest a better product for better results.

Rated 5 out of 5 by from Excellent Stuff! I used it to seal seams on my 1957 Chevy Pickup cab. Goes on nice and gooey and works easily into cracks, stays flexible just like description says, overall I was very pleased. I have used a couple of Eastwood products now and am very pleased with the results!

Rated 5 out of 5 by from Try it you'll like it I used it on the floor plates I just installed in my pickup. Easy to apply even overhead and adheres very well. Other brands were just to expensive to try and silicone caulking is only good for a temporary fix. I'm happy I found seam sealer from Eastwood.

Rated 5 out of 5 by from Great seam sealer at a good price Used this for my inner cowl panel restoration on my 67 cougar. This sealer was easy to use and i will be purchasing more to re-do the factory seam sealer that is dry rotted. I recommend this sealer to anyone that is thinking about using it.

Rated 5 out of 5 by from Quick and simple Great grab at resent visit to the store. Just put a front clip on 99 civic cx. Made quick work of all seams. Went to paint just a few hours later, no problem with paint adhesion.

Rated 5 out of 5 by from Great product at a great price! This seam sealer was not only cheaper than the local auto parts store, it also applied the best out of all the brands I've tried. It made my race car project a little easier.
