Love this stuff!
This filler is absolutely amazing stuff. Really easy to work with too. I needed to fill so marks on some poorly manufactured body parts and found that the teo identical parts where different lengths. Decided to try building up the filler to lengthen one body part and its worked perfectly. Strong, durable and easily sanded and manipulated. Will 100% be using this product again. Also it blends perfectly to car when sanding so is totally invisible when paintedRead full review

Outstanding
Bought this to fill a couple of areas on some 3d printed parts. As they had a little flex I wanted a flexible filler so I didn't risk cracking but had never used one before so was unsure how flexible this would be and how easy to work with as I was worried it would be slightly rubbery and not easy to sand and shale. But, I have to say I was very impressed with this product. It's dark grey, so looks a little odd but once set it sands and shapes just as easily as normal filler. I'd definitely recommend this product!!!Read full review

Good quality product
This 2 pack filler is good and easy to apply. It is difficult to judge how much to mix because don't want run out of hardener which you get small tube. Would be good idea to show how many parts to mix on the tin side or small instructions with it. Can't comment on flexibility because used just on small plastic peace. Next will be using more on my plastic bumpers and front wing. Read full review

Does the job
Excellent stuff, works really well, strong but easy to rub down. Mixing instructions are a bit vague, but use the usual mix of golf ball size of filler to pea size for hardener and its about right.

Big Boy Flexible Filler
The best body filler I have ever used. Smooth to apply, almost cream like, strong, flexible and easy to sand. Other fillers can be grainy and brittle but not Big Boy Flexible Filler. It's so good I have stocked up a couple of tins for the future. Read full review

Super smooth when finished
Use it to repair a plastic moulding on a motorhome , I have used catalog many times in my youth but this product is far better, it mixes extremely smooth , adheres well and sands particularly well. . The moulding was smashed to pieces but with a bit of fibreglass matting and then this to fill , you would not know it had been repaired . Read full review

good flexible filler
I have used this on my fibreglass boat which is only 3 mm thick to keep the weight to the min. this filler is easy to apply and good for covering gel coat cracks before painting with hammerite smooth finish.Read full review

Works with nearly all plastic bumpers.
Easy to mix, easy to apply , easy to sand.
Your bumper can be as good as new with little hard work.
Saves going to specialists.
Brilliant concept.
