I used a black tar like sealant but tbh if it's corroding it's only a stopgap holes will just appear somewhere else.

You are eventually going to end up putting up new sections of guttering

I'll be looking for something like UV stabilised plastic guttering in future for anything I do and if that's not available I'll halve plastic piping and put it up..box guttering (metal) is only a headache waiting to happen down the line afaic

The sealant was no nonsense roof and Gutter sealant from screwfix....I picked a dry day, cleaned the Gutter and applied it.....thought it wasn't going to work and some of the holes once I got up there and started rooting around were big when the corrosion was taken off and needed a second application....was surprised it worked...and got the winter out of it but that section was on its last legs on inspection and no amount of sealing would work if new holes were just going to keep popping up...but might work for you if its just pinholes or give you the remainder of the winter in peace

There might be better products out there too

Pin holes appearing only last few days but they seem to be multiplying fast.

Where can you get the UV plastic large like the galv box guttering?

i used tec7 sealant on it last year and worked fine, but its riddled with more holes this year. its a joke.

was hoping i could get some pvc replacement that would just slide into existing without having to change brackets. think I'm been optimistic

I don't know...believe me I'd buy it if it was available ...as the box guttering I have is in the center of the shed V with two large roofs feeding water into it..its resting just above a girder with another girder to one side ...so essentially going through channel, I have no option to fit in a larger gutter in terms of width..if I wasn't constrained in width by the girder I was toying with the idea of splitting some corri pipe and making some brackets for it ...but the ones with enough capacity are too wide to fit and the smaller ones aren't deep enough to not overflow in heavy rain....I'd be thinking the 375mm would be about right for what I have...but it's wide and heavy ish...would need a good few extra brackets which I'd have to make up too...and then there's figuring out and endcap...maybe a jfc trough end and sealant...could use a holesaw for downpipe.....but to get another 10 years out of it I just went for replacement box guttering.

If there isn't a like for like plastic box Gutter available it might be a product there's a market for...I'd say there's a lot of the **** sieves in the country.

Anything new I put up is not going to have box guttering near it if I can help it.

Have a half round gutter on one shed the started to leak like with lots of holes, got lengths of heavy duty wavin pipe and split them in two with the grinder ( length ways) and sat them into the brackets and joined with tech screws and sealed the joints and worked a treat and won’t rust as quick as the galvanised gutter. A quick fix as had the piping from a building job.

The galvanised gutters are muck nowadays, I've replaced some on a shed built in 2014 2 years ago, but it's the ones closest to trees that are going first ,I was talking to a neighbour and he is making a good few gutters in stainless for lads now, I'll prob go that route myself,

how did you work fitting on the downpipes?

Thinking of using corripipe (cut inhalf) instead of leaking metal gutters and was thinking of running end of pipe into a plastic oil drum and have the downpipe coming down from that

What we had was a end galvanised done pipe fitting and tech screwed it and sealed it to the wavin pipe and a down pipe into two old diesel tanks connected to one an other to run a power hose. If we hadn’t the end we were thinking of drilling a hole and putting in a fitting to screw the down pipe too, and putting a heavy piece of timber sealed stopper and screw it into the pipe. Only one down pipe in 6 spans to collect the water. It took a bit of work to lift up the piping into place due to length but has worked a super job with no dirt sticking in the plastic pipe.

Gutter liner system might be what you need.

Or something like Sika Decothane:
