Review: Great product - This primer builds great and sands like butter. This will be my go to from now on Review: The thickest primer I've ever used. - This primer is great. I used it to clean up some bullseyes on my hood after fixing the peeling paint. I have used a good bit of primers in my time but I have never used a primer as thick as this. That is a good thing. High build is easy for sure. It's almost thick like a polyester sprayable filler. The hardener actually thins it out and makes it sprayable. Working time is very good and it dries fast. Was able to sand it 2 hours later. This is my new go to and only primer I am using. ## Features - European style multi-function 3 in 1 direct-to-metal primer - High build urethane primer with 4 to 1 mixing ratio - Excellent opacity and hiding power - Can be air dried, low baked or I.R. cured ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B003TQGGNM | | Best Sellers Rank | #16,464 in Automotive ( See Top 100 in Automotive ) #11 in Automotive Primers | | Brand | U-POL | | Customer Reviews | 4.6 4.6 out of 5 stars (538) | | Date First Available | April 20, 2011 | | Exterior | Aluminum | | Is Discontinued By Manufacturer | No | | Item Weight | 15 pounds | | Item model number | 2253-KIT-STD | | Manufacturer | U-Pol | | Manufacturer Part Number | 2253/2323_KIT | | Product Dimensions | 12 x 12 x 12 inches | | Special Features | Tintable | ## Images ![U-POL 1 Gallon (4.2 VOC) High Solids High Build Urethane Primer Kit with Standard (60 to 95 F) Temperature Hardener - Image 1](https://m.media-amazon.com/images/I/71EqiOfRI-L.jpg) ## Questions & Answers **Q: What is your highest build primer. Thanks** A: u-pol 4 to 1 mixing ratio **Q: Can body filler be applied over this like epoxy primer?** A: Not quite. The epoxy has a natural chemical bond with the body filler and it an be scuffed at 80 grit as well. For this, 2k glazing putty is a better option and can typically be spread over 180 grit scratches on this primer. **Q: can you top coat with lacquer** A: I have never used lacquer on top of this primer. I wanted to try it but haven't yet ,My thought is that if you start out with light coats of your color (topcoat),with plenty of dry time between coats you should be ok. **Q: will this stop reaction cracks from different paints.Use regular primer and getting cracks and weird seperation** A: nothing stops cracking paint., only maybe water base primer. best is stripping old paint and putting on u pol primer. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great product *by C***S on July 28, 2025* This primer builds great and sands like butter.
