I agree with everything thats been said.
heres my rules:
1. Make sure the surface of the joined metal parts are greese free, and clean.
2. Apply small blob of paste to joint, and slowly start heating up the parts, and paste, untill it runs into the joint.
3. Some copper wires need to be sanded using sandpaper- because they come out the factory coated in some kinda coating, which prevents the solid joint.
4. Use the heat sink- i use the tissue soaked in water. I use the heat sink in close proximity to other joints.
One day i will show SBS from soldering.
Im slightly busy right now, but once the Christmas rush is over, an i finish repairing my van after the accident i will post the SBS.
Till then- practice, practice....
