  • Eastwood 2K Urethane Primer Surfacer Gray- Gallon 4:1
Eastwood 2K Urethane Primer Surfacer Gray- Gallon 4:1 is rated 4.8667 out of 5 by 15.
Rated 4 out of 5 by from A bit of a learning curve for the beginner. Goes on a little thicker than the spec sheets indicate. Comparing it to the other Eastwood products, this does not perform exactly as the spec sheets would indicate. It is bit more viscous and requires a 1:2 needle in the Concours Eastwood Gun or to open the needle all the way on a gun with a 1:4. All other adjustments on the gun should be open as well and dialed in as needed. I recommend you use 25 psi at the gun to start if you have a decent to high quality gun. Once you have the gun dialed in, this product works great and fills in nicely after the second pass. A third pass and most light imperfections are gone.

Rated 5 out of 5 by from great stuff!!! The guys at Eastwood know me and they also know I use PPG products in the shop. However, I decided to give the Eastwood refinishing products a shot and I am really impressed with the way this prime sprays and more importantly how easily it sands. I'll definitely be using more of their refinishing products in the future.

Rated 5 out of 5 by from Great primer! I used this stuff on a bumper cover repair with great results.Just make sure you use a tip larger than a 1.4 if you are going to spray large panels without reducing it. Overall, i am very happy with it and will be ordering more for my other restoration projects.

Rated 4 out of 5 by from Decent product I had to reduce this product quite a bit. It almost dries to fast but that could have been my reducer. It fills great and sands very easy compared to other brands I've used. I would probably be using this primer again in the future.

Rated 5 out of 5 by from Great Primer! Sprayed smoothly from an inexpensive HVLP with no reducer necessary. Flowed out great. I sprayed this without a paint booth, but was fortunate enough to have ideal temperature when spraying. The results far exceeded my expectations.

Rated 5 out of 5 by from Great Product! Great Primer! I have just tried this primer for the first time. It sprays on real well and sands very nice. I should have used more reducer and then I would not have had to sand so much. However, this is a very good product and dried quickly with no runs, drips, or errors. Thanks Eastwood!

Rated 5 out of 5 by from A Favorite I sprayed this with the "Contour" gun with a 1.8 nozzle. I found I had to reduce it with one part reducer to get it to spray well. It fills minor imperfections beautifully and sands to a very smooth finish. The adhesion is excellent. Would definitely use it again.

I have been using some Martin Senior 2k urethane primer/surface, I think it was tp520. Because of the low voc requirements they do not have it available any longer. I am looking for a good primer/surface/sealer. How does this one compare?

Asked by: Rustyman
This product is directly comparable to any other automotive urethane surfacing primer.
