Rustoration Question - Seal, POR-15, Primer, Advice on the order applied Options

[Larouex]

Hi,

I am getting close to finishing up my rustoration on the passenger side of the car and I have looked over lots of other rustoration threads on the forum and have not been able to come up with a clear idea of the order I should apply my protective stuff.

Should I…

Option #1 – Apply Seam Sealer, POR-15, POR-15 Topcoat and then primer for Paint

*** -- or -- ***

Option #2 – Apply POR-15, Seam Sealer, POR-15 Topcoat and then primer for Paint

Any other opinions appreciated!

Thanks,
Larouex

Like the others have said. If the metal is rust free a good epoxy primer will work good. If you use the por15 I would also use the por tie coat primer then a top coat. Use the seam sealer on top of the tie coat primer as it may not stick to the por 15. Por15 dries hard and slick and paints have a hard time adhearing to it. Thats what the tie coat primer is for. You might not like the baby blue color of the tiecoat primer though.

Por 15 is really meant to cover rust that has been cleaned and treated with metal treat (ospho). Good epoxy primers are as durable as por15 but they should be top coated. seam sealer should not be used on bare metal if you are using epoxy primer it will seal and adhear better than the sealer. Put the sealer on top of the primer.
