Velcro'ed bodyshell

[DJ's Dad]

We've been to a coulpe of events now and seen the more experienced racers using velcro to hold on body shells rather than messing around with the little clips which always ping off and loose themselves.

We've just tried some regular velcro from Wilkinsons but it doesn't self adhere to the chassis - is there a knack to this or some special adhesive we should use?

Thanks.
