FAQs
Can I use U-Pol Easy 3 over bare metal?
While it has excellent adhesion, it is best applied over prepared surfaces or existing body fillers. For bare metal, ensure it has been properly abraded.
Is this the same product as Top Stop Gold?
Yes, U-Pol Easy 3 is the updated version and branding for the product formerly known as Top Stop Gold.
How thick can I apply this filler?
This is a finishing filler, so it is intended for thin layers. If you need to build up depth, use a dedicated body filler first.
Does it come with a hardener?
Yes, each container includes the necessary hardener to initiate the curing process.
Can I use this on plastic bumpers?
This product is primarily designed for automotive body panels. For plastic repairs, ensure you are using a filler specifically rated for plastic substrates.
Troubleshooting
Filler is curing too quickly
Use less hardener next time, but ensure the ratio is still sufficient for proper chemical curing.
Surface remains tacky or soft
The mix was likely insufficient or the ratio of hardener to resin was too low. Scrape off the uncured filler and re-apply with a properly mixed batch.
Pinholes appearing during sanding
Ensure you are using a clean spreader and pressing firmly during application to push the filler into surface pores.

Setup, Compatibility & Care
To prepare, ensure the surface is clean, dry, and free of grease or debris. Abrade the surface with P180-P240 grit sandpaper for maximum adhesion. Mix the filler with the included hardener thoroughly until a uniform color is achieved, avoiding air entrapment during mixing. Apply in thin layers to avoid sagging or excessive build-up. Once cured, sand with progressively finer grits, starting with P240 and finishing with P400 before priming. Store the container in a cool, dry place and ensure the lid is sealed tightly to prevent the filler from drying out or degrading due to moisture exposure.
