using por-15 in upper engine bay

Hello all.

I have carried out a number of repairs the the floor pan and rear arches of my mk1. So when everything was done I stripped to bare metal and used the por 3 step process on the complete underside and inner arches of my golf.

happy with the results.

I ve also done the lower engine bay.

Ive now stripped the engine bay itself back to bare metal and I was gonna etch prime it but i am now considering using por15 as my base coat. I would then spray a few coats of high build over this before colour coat.

They say por15 it can be used as a primer so Im really considering using it.

Any one ant thought on this?

thanks

the promble with por is that nothing sticks to it

they do sell a ti coat primer that goes on top or por with means you can use celly or 2k on top

frost sell it

use that and you should be fine

thanks for reply.

I taught after sanding it back for a smoother finish and to give a key for the primer,
 the primer would stick to it?

If not ill get the tie coat and hope that works.
Or ill etch prime it, high build, colour coat etc.. With bare metal, do i need to be getting some sort of protection on it as soon as possible? Its been back to bare metal for a wwek and is still nice and shiny.

also you mentioned that nothing will stick to it but i presume for the underside, the stone chip will have no problems sticking to it?

por is a very strange paint

you must uses the tie coat went over spraying esle theres a chance the 2 paints will react

read the about the tie coat on frost website that will explain all

This top coating problem is one of the reasons I switched from por15 to epoxy primer (rustbuster) - and it's much better.

Frost say that you can just key up por 15 with wetndry - I only discovered this after putting celly down onto por15 in my caddy bed then having it flake of about 3 months later.  

thanks for the answers. Im going to get some tie coat primer and use it over the por-15.
I hope it works!
