I think the way I did it is stronger, but if using Bondo works, and lasts, who cares? There is not only one reason I do it with fibreglass, but several. It may be mainly that I really like grinding and laying down fibreglass. Really therapeutic for me.
I have four more belly bands to go, probably more in the future. I will still use fibreglass. I am a slow worker. I think I could do it in a weekend, if my kids did not require my attention, and the moons are aligned. But since I only put an hour or two in at a time, it takes longer.
Prep, (news paper): 1 hour
Grinding: 2-3 hours
Removing the metal plates: 4 hours
Grinding the sockets: 1 hour
Laying the glass: 4 hours
Grinding back to the gel coat: 3 hours
Sanding flat: ??? haven't done it yet
An estimated 16 hours to do what I have done. Other then the brown fibreglass showing, it looks good. I guess I am pretty good with a grinder. I think a few hours with the orbital sander and I might not need any bondo.
In preparation for launch day, I am going to do a complete referb of Launch Pad, this summer. This includes re-install the windows
, re-install the door, and belly band. This time, I will try to go fast on all three. I will try to keep a log of the hours I spend.
The door was way easier then I though it would be.
