U-Pol Products 2251 System 2025 DTM 2K Hs Urethane Primer Filler - 1 Liter

I really like This primer. It self levels to a very nice finish. It's a little work to wet sand due to its hardness but sands to a very smooth finish. It did not need a lot of wet sanding as the surface was very smooth as sprayed. This primer is very very thick. I think you could even just add hardener with out reducer and use it as a glazing compound. Typical HVPL spray guns will not spray this with out reducing alot. With this primer you are buying primer and not a lot of solvent. Unless you have a spray gun that will spray cold honey you will need to order reducer as well as the primer and hardener. I mixed it 4:1:2 and 4:1:3 primer::Hardener:Reducer depending upon application. I used a 1.4 mm HVLP at 45 psi. When mixed 4:1:1 it would not come out of the gun.

Must been really old, no good

This is a fairly expensive 2K Urethane, but it also does what it claims. It is High-build. I wish that high build primers went on without so much orange-peel, but even with quite a lot of reducer, it didn't seem to take out the orange peel. Since it needs to be blocked and sanded anyway, this really isn't an issue until the final coat. I'm a raging novice, so that is possibly part of the problem, and I could or should have used something else for the final coat. Never-the-less, it did what it should have and the project came out very well.

The advertisement stated gallon but was sent out quarts instead of gallons. They could not even take care of the error.

First time using this stuff. Have used other primers in the past. I really like this stuff. Goes on nice, sands easy.

Great product for the money , fills great just like expensive primer , spray it with a tip bigger than a 1.7 or you'll have to reduce it...

Great primer

easy to mix and good finish
