I hit with a curb, there are scratches and small holes. Do I need to use this alone or with other product?** A: the filler works just the same as any resin body filler but is for plastic items as opposed to metal. (its more flexible when set and sticks to plastic better than regular p38 isopon or plastic padding). dependent on the size of the holes you might need some kind of support for the filler. if holes more than 2-3mm i would stick a bit of fine metal mesh over the back of the hole and let that dry before filling the front of the hole. then sand, degrease, prime (plastic primer!), paint and lacquer as usual **Q: My back plastic bumper has been put right through with a towing bar, so there’s a hole.. would this product be enough on its own to repair the damage.** A: Depends how big the damaged area is. The dent I repaired was the size of a golf ball and it had a hole. I did not have to use all the sachets. It does a very good job used with the correct abrasive papers to finish. I think the final smoothing was done with 1000 grit wet and dry. I would recommend the product. **Q: Can this be used on arb plastic on caravan panel?** A: Yes. I’ve used it on plastic bumpers, works well **Q: 4 x filler sachets but only 1 hardner sachet ?** A: You only use a small amount of the hardener relative to the volume of material in the filler sachet. The hardener pouch is resealable. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Squeeze and go plastic bumper filler! *by J***. on 1 September 2025* Very pleased with the Isopon filler in this tube application.
