Cheers Scotty,

Been flat out everyday working on the GTI. It's a matter of work, and then work on the car straight after work till late...
Had a win with gunky/ rusty fuel tank.
Bought some POR 15, automotive fuel tank repair kit. Probably the best $160 I've spend. The kit came with 4 litres Marine Clean, 1litre Metal Ready, 1 litre Tank Sealer, Patch cloth, Pouring spout and inspection mirror.
First I used the marine clean to break down all the gunk. Used some really hot water and it worked a treat.
Next the metal ready, which is basically a prep for the Tank sealer.
And lastly the Tank sealer.




The trick was to make sure the whole tank got covered. You have about 20 minutes for that as it starts to cure.
It takes about 3-5 days before you can pour fuel back into the tank.
So that's another job ticked from the list!
