A few people have been scammed on the site, Only use paypal to pay for items for sale by other members. If they will not use paypal, its likely a scam NEVER SEND E-TRANSFERS OF ANY KIND.
I used VHT epoxy paint on a frame repair of my last bike. Highly recommended.
The repair was exactly where a skid plate would be, and on a cruiser, so the frame was exposed and low to the ground. The paint worked great, and was super tough. Looked like new for a year up until I sold it...
I use the rear brake mostly. If I need to put my right foot down, I'll let out the clutch enough to hold the bike. The NC has enough torque at idle to hold itself on most hills.
