I get Valspar hardener at my local Fleet Farm store but they're only in WI, IN, MN and IA. Fleet Farm is our regional farm supply chain so many your local farm supply carries it.

 

I think I just saw Valspar hardenar a Tractor Supply Store

 

Tractor Supply has hardner for their tractor paint. I have used it and had no problems using it with their paint.

 

Thanks fellas. I am not sure if we have Tractor Supply here in Tulsa. I am a Kentucky boy and I know Kentucky has tractor supply. I think in this area its ACE and Atwoods. There is an Atwoods three miles from the house so I will check them out.

 

I don't mean to be contradictory, but, their web site clearly states that it is UV sensitive and will fade to charcoal grey if not top-coated with an opaque paint.
As well, if it is over coated the surface sheen and color are essentially irrelevant as an opaque top coat will be what determines final color and finish.
I have heard that it is less viscous, and thus easier to apply, than POR-15.

 

I also think you can apply paint right over most of these types of paint except POR-15. At the last time I used POR-15 you had to buy a couple of more of their expensive products to make the paint stick.

 

Sorry, not sorry. Dragging this thread up from the bottom of the oil pan.

I'm getting ready to paint my 16 foot long horse trailer inside and out (which will be pulled by my Ford so this kind of counts). I've used the Rust-Oleum clean metal white primer on my trailer and have started wet sanding.

I have many questions and would really appreciate it if someone would help me out a bit here ...

I have 2 gallons of Rust-Oleum gloss white professional paint
I have a gallon of Sherwin Williams 3rd dimension paint in white and 2 bottles of hardner.

1. Would 1 gallon of the sherwin williams paint cover a couple coats worth inside and out?
2. Will that S/W stuff spray over the Rust-Oleum primer ok?
3. If not I'll use the rustoleum
4. Will the hardener for the Sherwin Williams paint work in the Rustoleum
5. If not, what hardener should I use with the rustoleum? Can I use the hardener for the farm implement paint at Tractor Supply?
6. Would the Sherman Williams single gallon be enough to paint an F250 Super Duty and what primer should I use?

Thank you in advance for your responses

 

There is an additive called Japan hardener that works perfectly for rustoleum .Its commonly used by professional house painters that have to get in and out quickly .Its real cheap ,$4.00 will get you enough for several gallons of paint ,it just takes a few drops .Sherwin Williams has it for sure ,not available at Home Depot or lowes around here .

 

Well this is super frustrating.

I emailed RustOleum about a week ago and they FINALLY answered me today.
Sharp customer service, I tell ya. A whole week huh?

So THEY said do not use acetone and do not use hardener and to thin with mineral spirits only. I have first hand experience at seeing how unhappy acetone makes Rustoleum pro. paint.

*stabs self in eye*

 

I used Rustoleum on the chassis of my '46 Chevy. It went over their heavy rust primer. I didn't take note of fast it dried but I do recall that it had a nice shine to it and when I packed the whole truck up to ship to Denmark, the chassis looked great! Oh, did I mention I had a 351M with C6 ready to go in the truck? Was planning on going against the grain with that one.

Later!

You said in the post above that you are wet sanding the primer, if you put that work into a paint job then use a good paint and finish the job with the same effort that you put into the sanding

 

Personal opinion, that Rustoleum primer is worthless *#/^&. I'm surprised you can sand it. Stick with Rustoleum over it.

 

I have a gallon of Rustoleum Pro black that I bought to paint the floor boards on my F4 bed. I specifically says on the can to ONLY thin with acetone.
