Recently we had an incident at the club where a fire in an adjacent premises caused the fire brigade to spray water over a huge area of roofing, culminating in some water ingress and some of it landing on our track. this, needless to say did not do much for the affected slots o our pristeen MDF slot car track.
Repairs have now been made in a very effective manner and this process is suitable to use on ay MDF / chip board track where slots may become chipped or worn over time. here is the easy cure in photos.
