Comment on Fiber Reinforced Plastic Armor Tutorial by Wilkowen
Interesting idea! I hadn't thought of using polyester resin with materials other than fiberglass.
One note, though - polyester resin and body filler should be used with a respirator, as they give off toxic vapors. You're probably fine once or twice, but using it for long periods of time or repeated exposure can cause neurological damage.

I think that a lot of the concern about using these chemicals at home comes from the misconception that the same exposure hazards found in industrial applications also apply to DIY projects. Even so, I will probably remove the statement that a respirator is not needed for this small project, and just let folks decide for themselves.
True - a lot of stuff depends on degree of exposure (ie, frequent for industrial uses, more variable for people doing DIY stuff - I know I didn't have what would qualify as 'proper ventilation' when I did resin work, though). In general it's probably better to err on the side of caution - and respirator filters are the only thing that'll block out how awful the resin smells *g*
