If the leg is unconnected and is very likely to be subsurface then car I think may not help, where will the air go and how will the resin get in? However if the legs is connected and just hard to fill and does not have moisture in as I mentioned earlier then some heat can help. Althoug I prefer flexing and holding. We have guys in for trainig that have been shown to flex a leg by just giving it a quick push, when flexing what you are doing is holding the leg open wider to allow the resin to flow. So when you flex hold the pressure until you see the resin stop flowiing and then release go onto to vacuum for a while and the pressure again if needed.
