need help

[craden]

hiya guys, im currently working on an iron man costume and have recently got myself a lid. i beleve it has been made with jesmonite aka aqua resin. there are a few places where it will need filling as there are quite a few air bubbles. Will i be able to sand this down where there are inperfections? So if anyone could guide me into making this right it would be much appreciated

heres the pics

you can just use body filler or even spot filler in these holes, i have used it for the same thing in the past.

Make sure to not over do it with the filler/bondo.
ive seen WAY too many iron man builds where the cake the stuff on there....

Good luck man.
