U-Pol 2K HS Build Primer 3:1


Complete spot and panel repair jobs easily with the high-solids two component urethane coating, offering a versatile performance. The U-Pol 2K HS Build Primer 3:1 coating can be used with a hardener, and it works like a spray filler. When you add one-part reducer to it, this primer will work as a urethane surfacer for panel and overall repairs. If you increase this amount of reducer a bit and add hardener followed by 1 ½ parts of reducer, then this formula becomes a quick drying sealer that aids repair jobs as well.

How to prepare the surface before using U-Pol 2K HS Build Primer 3:1:

  1. Wash the surface properly with soap and water, and dry
  2. Degrease the surface using a suitable grease and wax remover
  3. Sand with 180-220 grit sandpaper and clean again with a grease and wax remover
  4. Apply etch primer on the surface before applying the primer filler for enhanced adhesion and corrosion protection over bare metal

Been restoring classics for 25+ years and this is an awesome product. Just as it claims, 3 products in one depending on reducer ratios. Straight 1:1 makes a great Featherfill substitute with the pros of a 2K product. Great primer surfacer also. Upol's hardener is also versatile enough to use in a wide range of 2K products too.

It dry sands great, sprays perfect out of a 2.5 tip. The manufacturer recommends a 2.0 tip but it can barely be done, had the fluid knob cranked all the way out and pressure jacked up higher and it still wasn't laying right. Ran it through the 2.5 gun shot great. Used up a whole gallon in a matter of minutes though with that massive 2.5 tip

This primer is almost as good as diamont DP26. The one notable difference is, it doesn't dry sand as easy . All the other atributes are about the same but, the DP 26 can cost over $340 for a gallon kit.The value of this product is hard to beat,I love it!
