## Questions & Answers

**Q: Hi, have a steel mount field lawnmower deck and have some holes appearing - would this be suitable? Thanks**
A: Provided the holes not too big remove the rust and fill. It's easy to sand flat to a smooth finish. Anything structural you'll be better with fiberglass filler

**Q: Can you get a polished finish with this?**
A: No not realy

**Q: can this be drilled and tapped?**
A: It can be drilled and tapped but it won't have the same strength as metal so won't hold much torque

**Q: need to fill a plastic hole+crack in a chair foot, but prefer metal like strong materai, will this work?**
A: I don’t see why not the filler dries very hard.

### ⭐⭐⭐⭐⭐ Good stuff

Good price fast delivery I use this to fill minor damage on alloy wheels it is good quality works well easy to mix easy to sand with good adhesion Recommended

### ⭐⭐⭐⭐ Good filler, mixing is difficult
*by R***M on 19 October 2025*

This is a great product, does exactly what it says on the tin, fills, sands to a smooth finish and easy to use and mix, except, the instructions suggest mixing half the of hardener, which comes in a small squeezing tube with half the filler in the tin, problem is there is no way to measure with any accuracy half of either. So having prepared the surfaces to be filled I duly measured out what I considered half and half in a separate container and started filling, I worked quickly, however within five minutes it had set hard making the still to be used filler unusable. Being more careful with the other half mixing smaller quantities I managed to finish the work. It would be great if the manufacturer could provide some better means of measuring out
