Removing sealant from rain gutters?

Hey all.
The sealant in my Patrol's gutters is looking a bit aged and starting to crack so I figured I'd replace it with some Selley's sealant but had two questions for anyone that's done this:

1. How did you remove the old sealant? I took a flat-blade screwdriver to a small section and the stuff was quite tough to stab through. Could work but definitely not very elegant.

2. Which Selley's would be best? I thought the marine silicone product because it'll be good with UV, it'd be tough in weather, and flexible.

Cheers.

Its called drip check Im thinking a hooked scraper of some description.
You talking about the gutters on your Patrol

Yeah mate, the gutters on the Patrol. Probably best I don't call them rain gutters, bit confusing eh.

Hey UV. I had to fix a small section on my 3L few years ago. As TD said, the product I used was Drip Chek.

Not sure if any of the sikaflex style products are up to it
as you already know its tuff stuff and tuff for a reason.
Id seek out the correct medium to fill it. Yes sikaflex will
work but its not the right stuff

When I asked the Chemist for something to stop a drip it didn't look anything like that I can tell ya...

I'd be inclined to leave the factory product in place and run a bead smear over the whole lot. Much less work. Same outcome. I would use a Sikaflex product only because I've never heard of Drip Check.

IMO I think any of the Sixaflex products would have too much give,
Thats a long seam and any twisting and flex would be greater with
a sikaflex product

Hey hodge, 3D -
I found some auto restoration blogs that also recommended 3M Heavy Drip-Chek for gutters so I'll give it a go. It doesn't seem to be stocked by the usual auto retailers, only found it at Blackwoods - does that sound right? My nearest Blackwoods is an hour away so I'll have to eBay it.

If there's some surface rust in the gutters, what's the best treatment? I've used Ranex Rustbuster before but it leaves a residue, so what about some Penetrol spray?
