I've never worked with the materials that you're using so I don't know how it'll hold up to this, but I think you should just try to sand (or dremel) the lumps and fill the divits (with a suitable material) first.
If you just apply the plasti now it'll pretty much be the same but with a rubberized finish.
Depending on how many layers/coats you want to do with the plasti, you might try applying the plasti till all the divits are filled and then sanding/dremeling the lumps afterward.
Interesting;
So I take it the plasti dip is sandable?
