Sorry if this is the wrong forum...So I'm trying to carry out a repair on a alloy item that has a small hole in it using HTS 2000.
I can make a repair without too much problem but when I go to remove the excess HTS2000 I'll find a small hole that was not visible until after the clean up. What I don't seem able to do is add any more HTS2000 to fill the hole. The rod just wont seem to catch to start melting. I'm pretty sure that the metal is getting hot enough as I'm using the same technique to heat as before - even giving it a pre boost so to speak in the oven. I've tried roughing it up again in case its that, as that's a pre req. Ideas that cross my mind are that I'm contaminating the rods by accidentally getting them into the torch flame (as I know you are not supposed to do this) or that applying the flame to the existing repair in some way seals it?
When I have been able to get the rod to melt again it then tends to melt part or all of the existing repair which is pretty frustrating (if not unexpected)
Ideally I would not get a hole or air bubbles in the repair to start off with, although having said all that another part of me wonders why I'm being so perfectionist about it as the paint will probably seal the holes near enough anyway - I just find it hard to walk away knowing they are there.
