Hi. I did my two vans with protecta coat before I had the systems fitted.
Tips.
1. Make sure the floor is dry and dust free.
2. Mask off the side about 2 to 3 inches, take time so it looks neat. Paint the edges first then remove the tape before it drys and then paint the floor.
3. keep stiring the paint as it has rubber bits in it to give it the non slip.
4. Use the brush with the kit for first coat wrap it in cling film or foil then you can use it for the second coat next day.
5. If the van is ply lined and is in good nick seal the joints and leave it down.
Mart.
