## Description

Silverhook BIG31 Big Boy Plastic Flexi Filler 250ml : desertcart.co.uk: Automotive

Review: Quick and easy to apply and sand to shape - 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).
Review: Good product - Nice product worked well for what I needed

## Questions & Answers

**Q: My drivers side door is a bit bent in and rusty at the edge. If I tap it out level will this be any use to cover the rust and any gaps?**
A: If you go to the trouble of "Tap it out level" you should also want to remove or deal with the rust, before you try to level the contours of the door skin with a filer. Whilst I assume your car's door is not plastic but metal, I would expect you could use this filer but it should be noted it's prepared for filling / bonding to plastic items, therefore it should be recommended that you use a filer designed for use with metal!

I hope this info. is useful to you, and I wish you the best of luck / success with this project, and remember to treat / paint the door skin to preserve its future life / service!

Regards,

David Head.

**Q: Has anyone used this on upvc window frames**
A: I used it on some motorbike plastics and it’s done the job. Can’t hurt to give it a try.

**Q: I have some deep gouges/scratches to fill on a dk grey bumper which I intended to treat afterwards with the forever black product..will that work ??**
A: i used this product to fill a large dent in my back bumper, it seems the previous owner to my van had reversed into a post.it filled the gap very well and after hardening it was very easy to rub down with sandpaper.i then used black bumper paint spray and gave it 3 coats and it came up really well.if you have a dark grey bumper you might like to purchase a bumper paint spray the same colour.hope this helps.

**Q: Will it be OK to fill dip in caravan roof, where water collects**
A: Id be guessing,but I think it probably would. I dont know if it would be water poof or not should there be  joint in the roof covering at the area of the dip.
Good luk
