Geez, one chrome pipe and suddenly you're "Mr Chrome"
I used 2 pack - the brand name I can't remember. I could find out if it helps. Bought it from a paint wholesaler in Cairns. Chosen from about 200 colour swatches on about 10 books. I took the old swingarm along for comparison. The best I could do was GM Silver.
WMC - I have 2 125H's and a 125J on the waiting list, so I'd be very interested to know how you solved the steering head issue.
FWIW I used gloss black rattle cans for the frame - that was when I started off on a budget - sadly that went out the window - not exactly sure at what stage. Others prefer powder coating. I went for satin engine cases and hubs, gloss barrel, claer coat head (yet to see how it handles the heat)
