Krylon vs. rustoleum update

[joesquid]

I know everyone has been waiting with baited breath to hear how the shelf paint test is coming along.  For the uninitiated, read here:
krylon "rust tough" vs Rustoleum "hammertone"

At the end of the first month I've found that the rustoleum seems to have a lead on the krylon.  I checked for wear, dullness, flaking, and rust.  At this early stage I didn't expect to find many signs of these but the Krylon surprised me.  While it did keeps it's sheen, it was obvious to the touch that the paint is in early stages of lifting, strangely enough, it's more pronounced on the underside of the shelf.  To they eye, the paint is bright and there is a definite difference between the unfinished and finished shelves.  The deformities on the unfinished shelf are much more pronounced after just one month use.  What they eye doesn't catch, the fingers do; namely a rough sandpaper like texture that leaves residue on the fingers or a cloth when wiped across the paint.
In contrast, the rustoleum looks as fresh as if I had just laid the paint yesterday.  No signs of wear, flaking, dullness or rust.  At this rate I may not need six months to determine the winner but intend to stick it out anyway if for no other reason than to see longer term exposure effects.  In all attached pictures, the unsanded (unfinished) shelves are on the left.

Let me know if you have any questions! One last note, all shelves were actively used and reloaded on a nearly daily basis using plastic and glass bottles.

hmmm let me try the pics again!

I'll take another look at the pics and try reposting later.  Sorry about that!

Good to hear that the rustoleum is in the lead.  I just finished painting all of my shelves with the rustoleum.  Can't wait to finish the machine and get the shelves in use.

Great Job keeping us informed.....
I may be doing a whole tub... I had my 81 tub liner sent to be zinc and AFTER they
gave it a acid bath they said they couldn't keep a even coat on it so they sent it back!!!!!!!
Ahhhhhhhhh!!!!! So now I have a nice tub stripped of the light surface rust from the bottom
and back and ALL the galvanized finish.... It sits in my basement in front of a de-humidifier
till I figure what I can do to make sure it doesn't rust now.

I'm thinking of having the whole thing chromed.... Powder coating can scratch and am afraid
if I just do that and it gets scratched it'll just get moisture under the paint.
So I again I'm thinking Chrome then Hammertoning the thing to double sure it won't rust?
What do you guys think?'>

Okay,
i'm going to try the pics again.  The first set is the Krylon "Rust Tough" Battleship Gray shelves.  The unfinished (unsanded) shelf is on the left.

Here's the backside

Here's the rustoleum shelves.  The unfinished is on the left.

...and the backside.  Rustoleum is winning so far.

Eric,
I ran into a similar problem doing a tub once.  I just used the Rustoleum hammertone (no primer) and put three coats over the entire tub.  It sat in my environmentally unfriendly garage for an entire year while I slowly finished the rest of the machine.  This was in Pensacola, Florida; a hurricane happy, high humidity kind of he**. Never once showed any signs of rust.

And no that wasn't a plug for Rustoleum. '>

Chrome plate the inner liner? $$$$$$$$$$$$$  Noooo!

WOW!!!  After seeing the pics I am glad I went with the Rustoleum...they look great.  This is a great test that you are putting these through.

Thanks!  '>

I'm with Glen on this one!!! You'd better have a serious grip of cash to get an entire tub chromed! Just to get the Coin Entry Plate and Coin Reject Rod for my Stoner Jr. Candy Machine I spent nearly $100 bucks!!! And those two items are tiny!! The plate is about 2"W x 3 1/2"L!!

I would imaging the tub costing at least an easy $1000. For that much, you could have a machine shop build you a BRAND NEW liner!!!!  '>

[Eric]

WOW!.....  '> $$$$$$ Haven't priced the chrome yet.
What would you guys that restore all the time do?....

It looks like new since they stripped it.... but it's gonna rust
if I don't seal it some how........

Powder coating is really hard to scratch and there isn't much inside the machine that is going to scratch the liner. I would just have it powdercoated.

Hammertone works for me!!! '>

[Eric]

As bothered as I am about it.. I'll probably do both..... powdercoat then Hammertone.
Don't want to put all this work and money in it for it to rust in a couple years.
Want this to last.........

Thanks all for the advice......
Eric

I went with Hammerite but prepped and primed with their special primer for galvanized steel.

Eric - Why would you do both?  My understanding is that powdercoat is tougher but more expensive.  Hammerite is almost as good and considerably cheaper.  As an fyi, I think somewhere in the forum was a question (I think from Josh) on whether or not you could effectively paint over powdercoat.  I can't remember if an answer was ever posted but might be worth a look....

[Eric]

Why both? I don't know... Just after taking this thing apart.... getting stuff chromed,
cleaned, media blasted and if I can get this thing back together I don't want to see
in a few years rust coming through and I like the look of Hammertone.
But powdwer coating is tougher... so here I am...

Yeah what ever came of that painting powdercoating?..... Don't want it to start
popping off either.

Thanks for all the tips and advice.... we'll see.... the ol' wallet will be the deciding factor.

Eric,
 One of the first machines that used hammertone on 7-8 years ago still looks like it was recently painted. It's all in the prep work. I wash with a high presure steam cleaner then I scrub the crap out of them with an sos pad and steam clean again. I then "brush" (lightly)sandblast prior to painting with hammertone. All the parts that are small enough to fit in my media blaster gets bead blasted. This works great for me.  '>

[Eric]

Sound good to me I'll Hammertone the 56..... Once this 81 is out of the way.....
Thanks All...
Eric

I like the hammertone but is there anyway to get that original sealer?

[joesquid]

What original sealer?  Can you clarify?
