Por-15
Por-15
Can we get this stuff in Ontario?
Hell, can we even get it in Canada?
If not, What is a good engine bay paint that we can get around here? I like the looks of POR-15 because it's a three stage brush on product that doesn't show the brush marks at all. Not to mention the really nice finnish. I refuse to use Tremclad because it dulls in a week or so, and it's a single stage that will not hold up at all (peeling/scrathces etc..).. I need quality stuff...
I'll try and get some pics of POR-15 jobs for you, just so you know the quality i'm looking for...

Por-15 is available from Quebec. I talked to them this morning and they say that to do the underside of your car( floorpan,Diff,&frame)the most you would need is 1 quart.This will give you enough to do two coats, which is recommended. It will dry to a hard glossy finish and will not show any brush strokes. The cost is $50.00 per quart + $10-15.00 in shipping + GST.They also said that you can paint it over any rust and it will seal it and prevent any more rust.
Their toll free number is 1-800-689-7504

I heard there is a 'system' you can buy from the makes of Por-15 that includes the metal prep (changes rust to zinc???). This is probably the one to get.
I've got spray undercoating on there now (black rubberized stuff from crappy tire). I wonder if I need to remove it all (ouch)
Anyone know?
Thanks in advance,

Yes you will have to remove it. The guy at Por-15 told me that to get the right application, it needs to be applied on dry,dirt free metal. Rust isn't a problem, you can paint over it.He said that it would stop the rust. If it is a painted surface you want to go over, you will either have to strip it or heavily rough up the area with sandpaper.If you have any concerns or questions, they are a call away. They were very friendly.
Damn, wish I had known about Por-15 when I stripped my floor and wheel wells 4 years ago. Looks like the rust is coming back pretty heavy in some spots even though I took it right down to the metal, used rust killer, cleaned thoroughly and used some heavy duty rust paints topped with rubberized undercoating. DAMN, is there no stopping it!!!!
I've bought it before. They sell a package deal for like $30 where you get a kit with everything you need to start. I was able to do the entire drivers side floor pan on my old 81 Z28. I've still got an unopened second package in my basement somewhere. I"m sure i got mine off the guy in Quebec. If you search on Yahoo for the POR-15 website, i think they have a link to the Quebec dealer, and you can order it online. Thats what I did.
Stevens Auto Electric- as mentioned above- has it on the shelf all the time and will ship sameday if you're in a hurry.
It will ONLY stick to bare metal/rust NOTHING else. The company's claims it will 'stop' existing rust are not exactly accurate. It is a polymer sealant that just so happens to come in different colours. When it is completely dry and applied on metal it becomes very rigid and air/watertight (for all intents and purposes anyways). However- when painted over existing rust- ANY air trapped under the paint will allow rust to continue growing and it will 'bubble' like any other paint/sealant.
Also- if you put it over a rust spot that is surrounded by paint- it will stick to the rust- but not the paint where the two overlap-so- water still gets in by leeching through the surrounding perforated paint (i.e. the paint 'ridge') and rust will continue from the outer edge inward.
It dries into a very hard surface- which can chip (like any paint)- so it has to be 'maintained' by painting over the chipped areas once a year or so.
It works best when it is applied and a finish coat of another paint (i.e. a Tremclad or such) is used to seal up any areas where the POR-15 meets another substance (i.e. like surrounding paint mentioned above).
Most of the products are not a 'finish' coat and in fact will deteriorate over time when exposed to UV light (i.e. sunlight)- meaning you want to top-coat in anywhere it will be exposed to sunlight.
-Don't get me wrong- I've used this stuff for years and once you are familiar with its limitations it can be great stuff- but it is not a great 'cure-all' for everything. It is by far much better than using say a regular rust paint (i.e. Rustoleum or Tremclad) alone- but nothing's perfect.

Probably WD-40 or penetrating oil might help too, but I'm guessing here.
