Paint compatability

[bones66]

I had my tractor weight bar welded recently as the strain over the years had began to take it's toll. To keep the welded areas from rusting I planned to brush on some Rustoleum primer followed by a coat or two flat black Rustoleum paint. Then after I applying the primer I remembered having a quart of Massey Ferguson Grey. Thinking this would look a little better and since I already have it wouldn't cost me anything I dug it out. The Rustoleum primer is oil based and the Massey Ferguson paint say's it's a "High Performance Enamel". Are these two compatible?

Why not test it on another piece. I always test different brands of paint to be sure.

Thought maybe someone had already been there done that and save me some time. If the test show some immediate compatibility problems I could handle that but don't want it to hurt long term durability or something that won't surface for a period of time. Hope my jabber make sense as I'm trying to do this from a smart phone an it's difficult to read! Sign of the times I suppose. Thanks

Without knowing exactly what type of paint the primer or your grey top coat will be, I will give you my 2 cents. Both the primer and flat black are likely acrylic enamels. If the grey doesn't require an activator/catalyst, it is also probably a compatible acrylic enamel. Even if it's the cheaper alkyd enamel, it will adhere and last OK. Alkyds typically just oxidize and fade quicker. Lacquers can be a problem to cover. Although you used flat, I would also rough up the surface a little with 200 grit wet/dry sandpaper. You can also check the MSDS to find the types of paints but I think you are good to go. Good Luck.

I would think both would work fine together, neither being a hi tec product. or exotic.

Both the primer and flat black are likely acrylic enamels.

They are likely alkyd, aka, industrial enamels.

The entire Rustoleum line of brushable paint is industrial enamel.

Farmer paint is usually low budget, low tec stuff.

Tsquared answered the question correctly. They will work together just fine. Stay away from lacquer paint. It will lift most of the base coats. Chalking will be the biggest issue down the road. Instead of sand paper, use a fine scuf pad. They work great in corners. Wipe down with a good wax and grease remover. Tack rag it, and then the fun part! Painting

Thanks fellows for the replies. Now you guys know what happened? Nicely painted weight rack............cruddy looking weights so I had to fix that problem. .........Now all that bright factory color on front make that front grill and grill frame look really bad but it has to stop!
