I've got two 135 degree bends in a (plastic) rain gutter where the bend was made (long ago, not by me) by gluing and riveting straight gutters together. They leak a little now, but being enclosed in metal fascia they are very hard to get at. I can barely get my hand into the gutter to clean it, let alone fix stuff.
I was wondering if there is some kind of product available that could be brushed over the area of the joins to seal them? If not - would roof paint help? (I've seen enough gutters full of spilled roof paint to think it may "stick" well!)
The soffits under these two joins are being replaced soon, so I'd be able to apply any sealant underneath the joins as well as from above.
Any advice appreciated.

The only thing that will provide a very long-term solution is "car body underseal" which is a tar based brush on, or apply with a spatula, solution. Forget about anything that's silicone based. Try the major hardware shops or Repco for this. It comes in a yellow 1 litre tin. It's also the best you will EVER get for patching corrugated iron holes.

Awesome, thanks.

Awesome agreed. This is exactly what I needed to know too.

The glue that is supposed to be used for plastic gutters should do the job.

coltogum is good. It will stick to a wet surface as well so no need to fuss over getting it perfectly dry or keeping it dry till it sets http://coltogum.co.nz/

The PVC gutter cement will work as a sealer on the surface of PVC gutters. It works best when the PVC is reasonably clean & dry.
The trouble with the glue, for me, is full access to all the places that need covering, due to the metal fascia. I need a product that I can smear around with a brush; doesn't need to be too tidy. The stuff suggested in posts #2 and #6 seem ideal.

You could smear the PVC cement with a brush if you have to. You would have to be quick, and you might need a few brushes and possibly a few coats.
But it does work well as a surface filler on PVC

Coltogum would be perfect as maddie44 has reccomended. Have used it for repairs in old gutters before

What is your roof? concrete tile, metal tile or iron? If concrete tile just slide the tile back, same with metal tile. if iron then you have to unscrew the first few rows of screws and lift the iron. This will enable you to get to the area

OP did mention that the soffit is being replaced soon

The roof tiles are nailed on, not screwed, and as the leak is on a corner there's also the cap down the ridge line to deal with. So (re)moving bits of roof to get at the gutter just isn't practical.
Did get a brush-on product on the weekend, now just need some decent weather to try applying.

To be honest you'd be better off getting a professional to replace the damaged area of gutter. You have an internal gutter and any water leaking will go into your soffit and then inside. Not worth pissing around with

PVC guttering is as cheap as chips and by the time you bodge it and lay in bed at night wondering when it will need fixing again, what's a few bucks for peace of mind? Rip it down and replace it with new.

You have no idea what a bugger the metal fascia is. If it were simply about replacing some guttering it'd have been done in the time it took to make this thread.

What product did you buy? What shops sells Coltogum Water-Stop?
