Greetings;
I did not know much about rust converters and got advice from long time bodyman. POR 15, two coats, second one before first completely dries. Apply on both sides of metal when possible.
If there are no pinholes right through, O2 will be cut off and prevent further rust. We have used the POR 15 top coat primer but no experience on how other paints apply to it. cheers
