Probably going to get about 20 for my current project and next project. I've been using Toolpak from Toolstation, work fine, but anyone found anything cheaper, maybe if bought in bulk, e.g. 5 or 10 or twenty box?
Went for these, work out £3.80 each, lets see if they are any good:
I also bought these to go on the Dremel, I had one that came with the Dremel kit, they wear out quick being small, but worked good for me. I've had a lot of luck with using the Drenmel for bodywork repair. I don't know how others work but I cut out the absolute minimum of metal to get the rust removed. I'll use a Dremel cut off saw and little milling bits to make small and precise cuts. That way I avoid having to recreate complex OEM joints. Managed to patch up about four holes yesterday in half a day and did half of one sill. Just the other 20 holes to go
