I use bondo to fill in the bumps, mix a little at a time and fill it out, let it dry and re-sand it. Works fine for me.

To get a super smooth finish you need to spray a product called feather fill that you can buy at an auto body supply shop

just bondo sand bondo sand bondo and sand. Keep doing it till its really smooth. I use 80 100 and 150 grit for my sanding on bondo then when ur ready and its pretty smooth sand it all really good with 150 then wetsand with 330 then like 440 or somthing around there. If you have small dimples that are hard to fill with bondo go get a syringe and fill it with resin with hardener then make a little bump in the dimple with the resin, let it dry, then sand down to be level with the rest of the box around it. When ur all done with that stuff use a high build primer (found at walmart or newhere else, make sure its wetsandable) and spray the box a few times. Then wetsand with a paper around 400 grit.

the good thing about shooting a coat of primer on it is you will be able to see all the imperfections alot easier. I work for a body shop so materials are easy to come by. The biggest thing you have to have is alot of patience. If you rush it....its going to look like crap.....so take your time. If you sand to much down...you can always build it back up. when you get towards the end, i typically use like 600, 800 or higher. You can also take a razor blade and red putty to fill in any pin holes that you have ......if its going to be painted lt will show every imperfection so it has to be very smooth. once you primer and wet sand you will be able to see things coming together and when you look at the finish...do it in the sunlight of a well lighted area from different angles. Its alot easier to fix things before you paint it and shoot the clear coat. good luck
