I know there is a lot of threads here about RE and I read a lot of thoses but I still have a question! I’m planing of undercoating my car with RE, it’s not really for restoring but more for prevention since my car is a 2003. It have some suface rust at some places underneath and I was try to figure out if I should use oxysolv firt and then 2 coat of RE. Or just 2 coat of RE and heavy anti rust over it ? Does RE not top coated can last long of the underneath of a car ? What do you guys recommend me ?
