Tom Woods uttered summat worrerz funny about:
OK, right this is firm second favorite on grounds of cost and weight. Darren what thickness has been used on yours?
I used marine ply on a trailer rebuild years back, I recall it wasn't cheap then but I'll consider it if it's cheap enough. Other advantage to the grill other than the weight will be the fact it lets light through to the sunroof.
I do like the look of properly varnished wood I have to admit :-)
