I've tried for the past few years to install or repair aluminium
gutters in my house, but I've mostly failed in reliably getting leak
free installations (either at the downspout or when connecting 2
pieces).

I've tried different type of caulk or sealant but I've always found
them hard to work with (very sticky), as I can't use my fingers like I
do with regular latex caulk to smooth out the caulk.

Note that I have the Black&Decker guide to roofing/siding, but they
don't go into much details on how to apply sealant, quantities etc...

Do you have a brand/type of sealant and/or caulk to recommend, and
maybe tips to share with me ?

thanks in advance.

Can't help with caulking suggestions, but I'm wondering:

1 Why do you care whether your gutters leak?

2 Given the prevalence and low cost of seamless extruded gutters, is
there a reason you're disinclined to go that route?
