2nd Kenny V re: POR15. You can buy a starter kit which includes the cleaner, primer & POR15 for about $19.00 It goes a long way. I use it on my trailers, farm equipment, manure spreader, mowers etc. I would recommend top coating after curing as UV will affect the longevitiy of the product.
Did I mention that it's made right here in New Jersey, where the new state motto is better engineering through chemicals. That don't call this the garbage state for nothing..........
