rustoleum paint vs cat paint

[hicrop10]

I know some of you guys have said that you used the rustoleum paint instead of the old cat yellow.My Cat dealer can still get the old yellow paint but it is twice as much as the rustoleum paint.My question is that I have started to paint my Cat 15 Motorpatrol with the cat paint and still need about 2 more gallon,will there be a different in the two.Thanks Mike Durkin

The color maybe close, but the paint is different. The oil in the base is different than the normal implement paint. You may be able to coat over the implement paint, but will most likely will have problems if you put the implement paint over the Rustolem.

Check/compare the MSDS. As far as I know they are both Alkyd Enamels.

What is the part number of the paint you are using?

Looked up the "Old Highway Yellow" 4C-4185 and it's an entirely different composition than the Rustoleum.

As tw said, probably ok to put the Rustoleum over the Cat paint but not vice versa.

Appears Cat paints are a "Valspar" product according to the MSDS sheets.

The Rustoleum is definitely an alkyd enamel.

They are both Alkyd Enamels, but the base build is different. I am sure the anti rust paint uses a different base that makes it the anti rust product it is. Not all Alkyd Enamels are the same and compatable. I recently looked into getting a store brand of this paint to paint a pole barn. The prices were about the same, but the thinner was $20 per gal compared to regular paint thinner at $5 per gal. I have sprayed both types of paints. The Alkyd Enamels are not all compatable with each other. and not all hardners will work in all Alkyd Enamels. So do some checking before you have a pile of cottage cheese( non edible of course)
Just my two cents from being a painter for 40 years.

Sorry, I was refering to the Cat paint part number you are using.

Big changes in paint availability in Ca. with the latest low VOC requirements.....pretty much wiped out the polyurethane option, can't get the xylene/toluene thinners. Industrial coatings limited to 3.0 VOC, metallic coatings limited to 5.0 VOC

Can't get the zinc rich urethane primer I was using, had to switch to a epoxy-ester resin base version at 3.67 lbs/gal. VOC.

Not sure what Cat paints are still available in Ca. other than the water base stuff.
