I'd even recommend a couple of layers of fibreglass mat and epoxy resin (on both faces of the panel if you can get at them) rather than spatulas of bog - hard as nails, a bit more waterproof, quick and easy to work with.

 

Then you can do the final shaping with a quick skim of bog.

 

Anyway, looks like you've already tackled it. Many ways to skin a cat!

Decided I would do some work on my rims as they looked crap from previous owner spray painting them with rattle cans.

Btw they are 13" enekei competition limited edition rims.
