very nice.. now all you need is a big ass FMIC to fill up the top and bottom holes.. that would look sick!

as for bondo work i have used it a bunch and/or stuff like it on boats the more hardner solution you put in it the faster it gets hard so less hardner = more time to play with and perfecting and yea it is easy to sand but if putting on a metal surface be sure to seal it before painting because over time bondo will absorb water resulting in rust but if you plan on keeping the car for a year or 2 after the body repair then selling it then dont worry bout sealing it
