Re: Body Work How To (lots of pics)
I'm going to start out by saying that for an average do-it-yourselfer this might work fine. However, I do custom paint & body for a living so there are some things I don't agree with completely. My rant is as follows.
I don't understand the point of filling the dent with duraglass when you are just going to cover it with bondo anyways. Why waste the money on the duraglass?
I also have a few points about the write-up. If you are going to prime the bondo and/or bare metal then there is no reason why you can not use 80 grit to cut those areas down quicker. Any good 2K primer will cover and fill 80 grit scratches well enough to paint over.
Additionally there is no reason to prime the entire tank unless you are trying to fill nicks and minor imperfections. The primer does not need to be wet-sanded if you are using a good brand of sandpaper and 320 grit is widely used in the automotive paint & body field to knock down the primer. No additional attention is needed after DRY 320 sanding the primer and you can blow the piece of and go straight to paint.
I also agree with Andy gsxr on the "shrink line" as this is very common on quick paint jobs. I would recommend giving the bondo a few days to do what it needs to do and then do 2-4 coats of primer over the bondo to make sure that there is no "suck-back" as we call it.
If anyone has any questions on any of this I am more than willing to help out as much as I can.
