What would be better?

rubberized undercoat or bed liner for the underside tub?
Just stripped the factory crap off today. I was gonna wait to re coat for a while during the build, but figure that I should do it now.

Any recommendations on product would be good too!

Thanks,

Rubberized can go either way. It can dry, harden then crack and allow moisture to settle and create rust.

I would settle on a good industrail sealer(epoxy) ,then use the medium coat then the final.

I am sure there is a good rubberized coating out there like coal cat but its crazy $

You could just zinc the metal then paint to save a few steps.

There is so much good stuff on the market other than some of this crap people are using but you are going to pay.

Dont go cheap on a first coat if you live within the rust belt.

Check out some of this stuff. Welbeka( I am sure I spelled that wrong) may have few good suggestions also.

Im not in a high risk area as far as rust is concerned per se, but some of the trails that I travel DO (IMO) seem to have some waters that have a higher alkaline percentage? That is my personal observation of course and I have NOTHING to back that statement up other than exposed metal always seems to get rust after I run these areas in particular.
Im looking for clean, durable and relatively in expensive....
Thanks for the input. Ill have to look at that link a little closer!

PAINSTAKINGLY!!!!!!!!!!
I used a wire wheel for 80% of it...the other 20 percent was a combination of torch and scrape FOLLOWED by a wire wheel.
I plan to do the top ramp into the fire wall, I was OVER IT when I finished the bottom and didnt feel like draggin out the ladder to hit that upper section.

That would be webelk6;).

Any zinc product would be fantastic. Carboline is some nasty schitt to work with. Corathane is a 2 component zinc that is phenomenol.
I zinced my tub during resto and that tub sat in up and down temps for 2 ish years, and it did not have one rust mark anywhere.
A $100 or less would prime that tub in zinc.
If you do live in Chicago, you may want to check this website-

check the architectural coatings tab.
Good luck.

There you be:hillbilly:

So, you'd use the zinc as a primer, then paint over it!?
Interesting...
Does it have any sound deadening properties to it?

Thanks for posting up!

BTW...Im FROM Chicago and now live in Reno NV. We DONT use road salts here!:bounce:

Ive been told this as well and was planning on this step with either the under coat, or the bed liner!
BUT...if the zinc was reasonable, AAAAAAAN would also be a decent primer...

I know nothing about the zinc primer though.

Thanks for the input!
 
Both of us (the other crazy painter) used it in industrail . I will put it to you this way, it stands up to all weather ,heat,cold and all sorts of other chemicals without wear.

As a sound barrier.....not really.;)

Gotcha!
Thanks.

Anyone see any issues with using a bed liner on the under carriage?
Im kinda leaning this direction...
Anyone think of any CONS to this?
 
cruiser88 said:
Not if it has a sealer of some type first. I also thought the bed liner looked good:)

Oh yes! Of course Ill be sealing the PISS out of it first!
Picking up the caulking today, and I have a tub of the brush on gray seam sealer. I used that when I did the 1/4 chop on my 62 a few years back...that stuff was RAD!
Id like to keep the rattle down as much as possible is my main objective as far as sound deadening.
Ive got a few more pesky rust holes that Im in the process of cutting and patching, then its ON. Itll be nice to see SOMETHING on the rig at this point. I really started this project in oct, so Im getting a little tired of looking at the same thing day in and day out!

Thanks for the help!

Zinc can be used as a primer/finish. Personally I would paint a topcoat on it. The only issue (since it is bare metal) is to make sure whatever zinc you may use, make sure it will stick. For instance- On a metal building(galvanized) one cannot paint it until the "oil" in the metal has completely weathered, otherwise the oil in the metal will make the zinc peal.

etching primer might be the way to go before zinc.
 
Done!
Sealed with a combination of brush on and caulk seam sealant, the primed with some etching primer, then lined with Herculiner.
The Hippo liner I had used in the past seemed to go on better and more evenly...

Thanks for all the help Gents!

Thanks man!
I sealed the crap out of it, then that stuff is pretty thick to boot...should be pretty tight where the sheet panels overlap.
