POR15 & body filler

[Shuie]

Ive already POR'd the front clip of my car and floorboards. I had planned to paint every possible surface that could trap water with POR15 as well(window sills, cowl area, door latch panels, etc). After re-reading the thread Pat posted a few weeks ago, Im now thinking painting the whole car with it.

The POR obviously has to be applied to the bare metal under all the primer and top coat paint. I dont remember seeing any body filler anywhere on Pats SC. Im going to need to use body filler in a few areas on the car and Im curious if the body filler is going to stick to the POR paint?

Any thoughts? I know POR sells a filler that is supposed to work, but does regular plastic filler stick to this stuff?

TIA

I have the best luck with applying over POR-15, by doing so when the application of POR is still slightly tacky. This has worked great for me on topcoats, putty, and undercoating. If you are referring to POR that has already cured, I'd try applying some of their tie-coat primer before working with any other products.

I'd sand the Por with 100 and then use all metal filler, unless only a very thin skim of plastic filler.
