Isopon P38 Reviews

Our satisfied customers have found Isopon P38 solutions to be remarkably effective and user-friendly, as evidenced by the following reviews

I've been using Isopon P38 for over 15 years on my classic cars and it never lets me down. The 600ml tin is perfect for bigger dents and it sands beautifully smooth. Much better than cheaper fillers that crack or fall out. The original is still the best.

Emma Louise Carter

Bought the 2 x 250ml twin pack for some rust repair on my daily driver. Mixed easily, applied well and sanded down perfectly ready for paint. The repair has held up brilliantly through winter. Great product and fast delivery from the website.

Sophie Elizabeth Morgan

As a mobile bodyshop technician, Isopon P38 is my go-to filler. The Easy Sand formula saves me so much time and the adhesion is excellent on both steel and fibreglass panels. My customers are always impressed with the finish. Can't recommend it enough.
