I told you it was 'the daddy'! They look incredible now, eh. Sounds like you've used liberally rather than sparingly, though! Blimey, I've had the same tube for about 10 years and still loads left. Cheap enough
Yup, you were right! I put the bins out last night whilst it was pitch black and something glinting caught my eye... it was the exhaust tips. LOL. I used about 7-8 toothbrushes full (1 line top, left, right and inside per tip). But... looked like they hadn't been done in 35k. So hopefully I can go a bit easier next time!
