Ok, I have read it several times from cover to cover. Intresting stuff in there.

Now, I know the bottom of a Bugeye is supose to be the same color as the top. Hmmm, POR white on the bottom brushed on and good old Old english White on the top and engine bay, regular POR for all the inside which is under carpet anyway. Why not? Does this seem to make sense. Spray POR inside all the places that grow rust, and put some of that sealer stuff (can't think what it is at the moment) as well.

Supose this stuff really does as advertised, ie "stop rust permanently"

Now keep in mind that I am 67 so permanently for me is not quite like it might be for you younger folks and I do not want or need a concorse vehicle. It just has to look good and be functional. Well it has to look better than good in fact.
 
Do NOT use POR on any exterior surfaces as a finsih color.
It changes colors. In fact, painting over rust just hides it from view, it is still there and I had my floor pans fall out because the rust kept going UNDER the paint.
If it's rusty, fix it by cutting it out. If you hide it, it is just that. Hiden, and it will come back to haunt you.
Even if you are 67, do you want to fix it again when your 69?
 
Hoho, had no intention of hideing anything, was thinking of cleaning ie meda blasting then useing POR on the belly and inside the bug.

No, not the way to go?
 
I have used POR several times and places. Please, don't plan on using POR on sound, smooth metal. It isn't designed for that. POR needs a rough surface for good adhesion. It sticks well to chemically treated rust because the surface gives it a good "tooth" to lock into.

Media blasting is a good start but be sure to do extensive chemical etching with the Metal Ready in addition to the media blasting and do not put the POR on smooth metal, it will only lift off. It is NOT a particularly good primer under top coats either. You'll have better results limiting its use to hidden, rusty and rust prone areas.

A while back I documented my experiences with POR and put a PDF summary in my web storage space. You can read my comments by downloading that PDF from:

Doug,

That was excellent. Thank You.

Guess POR is really off my list except for consideration on the inside of the tub. And maybe inside posts and such.

I will be careful to follow all the instructions.
 
I have switched over to using Zero-Rust products <https://www.zerorust.com/> because they are so much easier to use and very effective. The local automotive paint store has many marine, restoration and industrial users of Zero-Rust and their positive reports convinced me to check it out. I do like some of the other Por products but Por-15 is just too complicated and messy to use.

Cheers,
John
 
Part of the Mini community has been experimenting with an alternate product called "Rust Bullet" (forgive my spelling... the product may be spelled 'Bullit'). Supposedly it offers the same protection as POR with less preparation and for a lower cost. I have no experience with it but it might be worth considering.
 
Rust Bullet<https://www.rustbullet.com/> sounds similar to Zero-Rust. Unfortunately, hard to compare results. Rust Bullet used Salt Spray test ASTM B117, for 500 hours(3 weeks)for one test and Zero-Rust says they exceeded 2000 hours on the ASTM B117 test. Unfortunately they haven't put the two products head to head. Anyway, both sound much easier to use and less expensive than Por-15.

Cheers,
John
