Silverhook BIG31 Big Boy Plastic Flexi Filler 250ml

This stuff is great , easy to use . Common sense , re the hardener is needed.

Excellent product, only issue was lid broken and tin dented in transit

Used this on a plastic engine cover project, a bit vague instructions on how much hardener to use but I found a data sheet online, only mix this stuff in small batches, the info says you have about 5 minutes working time before it starts to harden, so after mixing that’s actually about 3 minutes, once it’s start to set your chances of getting a decent smooth finish are almost zero, even tried mixing some up with half the recommended hardener, made no difference, having used similar type fillers before, i wasn’t too surprised. It did the job I needed it to, stuck well and sanded nicely, just wish the working time and a little longer.

Solid job !

Arrived promptly. Used to repair a large hole ripped in the front bumper (see photos). Applied using mesh and built up in layers. Cured in about an hour with warm air from fan heater. Sanded easily into shape using sanding block with a variety of paper grades starting coarse to get the correct form, and then a light grade before applying two coats of primer and the top coat (still needs a t-cut and lacquer but I am very pleased with the result).

The contents are only about half of the tin - very deceptive. I ordered one tin and then had to buy another tin, for the job I needed to doThe product itself is very good, but needing to pay twice was disappointing

Purchased June 2024 - 250ml £9.33 [Note: At time of writing webpage states both 250 & 280ml - 250ml was received - don't know if this "shrinkflation" or just a typo]We used this in very hot [for UK!] conditions and found it bonds extremely well even to painted surfaces, some applications required two-coats to fill in air-bubbles [probably user error]. Easy to sand and paint. Not much else to say - definitely use in a well-ventilated areaDownside - could do with a better way of measuring the ratio of hardener to filler, it was a bit of "hope this is right". We did find it "going-off" quite quickly, although this might have been down to the temperature +24 deg. C.Recommended

Did a good job of repairing some rigi plastic casing which had cracked.A quick sand down, wipe and then apply, and it had set within an hour.The instructions are poor though.... "use an equal ratio of filler and hardener... ie, use half a tub of filler, to half a tube of hardener"This is ok for big jobs where you can see you're using half a tin, but for small jobs I had no idea if I was using 10% or 15% of the tin.You should just give the exact ratio so we can weigh it out properly.
