Pine wood derby

I helped my 2 boys build pinewood derby cars,they both won best design,of course not in the same race,but,one was a 32 ford roadster,the other was a i cut the shapes out,then let the boys sand,sand,sand.I took the cars to work,and primed them with urethane primer,then let the boys sand somemore.Gabriel wanted his 32 roadster painted black with orange fireflame(dont know were they heard that from)and noha wanted his t bucket painted yellow,with whit prearl ghost flames.In the t bucket we found a model car engine,hemi of course,and drilled,and screwed it from the bottom.Both cars won best of show trophies,and the boys learned a lot about painting cars,and sanding.if you would like pics of the cars,i could take some for ya,im sure the boys dont mind showing them off.Have fun!
