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?

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.

Has anyone used this on upvc window frames

I used it on some motorbike plastics and it’s done the job. Can’t hurt to give it a try.

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 ??

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.

Will it be OK to fill dip in caravan roof, where water collects

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

Strong Adhesion - Easy To Work With

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 area Downside - 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

Product good, delivery poor, service mixed

The product did not arrive within the timescales advised which was a longer date than I would have expected. The product when it did arrive did the job I expected and was easy to use. When I chased I was told I could have a replacement or money back. I opted for replacement which was said to have been sent. I do not believe this happened but fortunately a couple of days later the original did arrive. So in summary if I need this product again I will source from another supplier.

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).

bonne qualité

Livraison avec Prime. Facile d'utilisation, durcissement rapide. Attention, procéder par petites quantité de mastic et ne pas mettre trop de durcisseur dans le mélange pour avoir le temps de travailler. Se ponce aisément.
