Rust Bullet vs POR-15

I just tried rust bullet, from a trial kit I bought some time ago and it really works.
I have both test kits one from POR-15 and one from Rust Bullet, so far I'm happy with the results from Rust Bullet and the lack of all the prep that you have to do with POR-15. Play the video
and make up your own mind.

Bud:

  I have used Rust â€"bullet and Por-15. While they’re both good and they both have limitations.

  Rust Bullet comes in silver only and you need two coats.

   Por-15 Gloss Black will break down from UV exposure and therefore needs a top coat- Not easy as this is so slippery you have to sand it or use an etching primer first.

   I prefer the Por-15 gloss black. You will note that in none of the tests do they ever use the gloss black, instead they pick Por-15 silver, which I think is vastly inferior to the black.

  There are rusty places where you can’t sand or remove the rust. Places such as inside heater channels, behind fender wells, inside rocker panels. This is where I have found Por-15 to be superior. I have patches holes using fiberglass and Por-15 instead of resin.
Because I can paint right over rust, lay the glass mat down and paint the fiberglass. This gives me a rock hard surface. However this is not my idea as I stole it from Hot Rod Magazine where they repaired a rusted out floor on a Chevy and repaired a rusted out rear window channels.

  While I never did any scientific studies, my neighbor gave me an old fold-up trailer.
It was an eye sore because the faded red paint was 95 % rusted. Every time I used the Por-15, I would wipe the brush on that rusty trailer-never sanded or wire brushed the loose rust. One of the unique feature of por-15 is you can push the paint. It seems that a little goes a long way. Anyway after some three years of whipping my brushes on that rusty old trailer, it was all black and it looked good, good enough that I was offered $125  and I sold it.

  One note: Gambardella Speed shop sells Por-15. No waiting for the mail if you need it fast- Same price as on line and no shipping charges.

Gambardella’s donated a $75 Assortment of Mothers products to our Christmas party for door prizes last year. I hope if you need Por-15 you will buy it from them. Also they can get you any of Pertronix electronic conversions for your VW and the correct coil in about 2 days.

AS I SAID ONLY MY  2CENTS
P.S. where do you buy your fiberglass mat.?
Thanks

Mat & Cloth are available at Pep Boys & I bought it at WalMart once

Careful...Know the difference between random strand fiberglass mat and fiberglass woven cloth. Mat can ONLY be used with polyester resin since it contains styrene binders that get broken down via the polyester resin. Fiberglass woven cloth can be used with polyester, epoxy or vinylester resins. If you use epoxy to wet out random strand mat, it'll be a sad day.

Not sure what resin base Por15 is, but I would venture to guess that it is epoxy based - unless it stinks to high heaven. I haven't used Por15 since around 1990...and I bet they changed their formula since then.

  I used the fiberglass mat that Por-15 sells. I also used woven mat I had left over from other fiberglass kits.

   With the woven mat you have to use more that one layer as the squares are large and if you only use one layer your left with holes.  :icon_clown:

To be clear for the newbies... Mat is chopped fibers....Cloth is woven

Thanks for the information. Now has anyone of you used fiberglass with Rust Bullet.  ???

Below is from Rust bullet's site-

Q: 14. Can I paint over Rust Bullet®, and if so what sort of paint should I use?
A: Yes, but it is not necessary unless you desire a color other than metallic gray. Rust Bullet® is protection in itself from sun, water, mechanical abuse and weather; however, we have successfully painted over it with almost every type of paint and coating. It is an excellent adhesion promoter and enhances the adhesive properties of any topcoat you may wish to apply.



I've used fiberglass with resin to repair the hull on  my  hovercraft.

 99off  Yo Bud... You've got a hovercraft?

Yo Bud... You've got a hovercraft?

Yeah!? I second that!

Had it since 1980, sold it a few months ago had a 485cc Yamaha air cooled engine in it.
Have pictures of it sitting next to my Ghia.
Jack and Joe T. saw it there awhile back. Sold it because my wife said I had too many toys  ./// Didn't use it much after I started flying my Ultralight out of Woodbine airport back in 93, I'm still transferring all of the hours of tape to DVD of flying over Wildwood, Cape May, Ocean  city etc. That is a "trike" with a  912 water cooled Rotax engine in it.
Our "kids" and grandchildren love to watch the video  of me flying over Moreys pier and the Cape May ferry etc. although they say I'm crazy and say your  are sitting in a lawn chair  BO** They love the video but wouldn't fly with me. Well I'm not allowed to fly anymore because of my age  etc.
BUT I still fly with my buddy when I feel like I miss it.
I still have all of the tapes and can relive those good "old" days.  :icon_cheers:

#1 - I've never seen the gloss black POR 15 break down due to UV exposure & I have a part that has been sitting outside for about 15 years. If you apply it correctly, it will last decades.

#2 - You CAN sand inside heater channels, rocker panels & other hard to reach places. There's a nifty little inventon called a sand blaster. Perhaps you've heard of it - works wonders!  :icon_thumleft:
