I remade a hopper for a potato planter out of stainless. I am getting ready to paint and was wondering if I need to prime it first. What do you recommend? ------------- Thanks & God Bless Dennis |

A major thing when painting is paint adhesion. Besides having the metal clean (especially of any oil), a good primer is a big help.

| Stainless does not need any rust protection. You could leave it as is. |

I'd have to agree with Stan, when you said stainless the first thing I thought was why paint it? ------------- Waukesha B, B, IB, G, styled WF, D15, 615 backhoe, 2-Oliver OC3's, 4 Ford Model T's, 3 Model A Fords, AV8 Coupe, AV8 Roadster, 1933 Ford Wrecker |

| Some metal parts and some equipment I have welded and built, I take a torch and heat the metal up and you would be surprised how mush moisture is in metal. I have heated 1/4 to 1/2 inch metal flat steel and the water will bead and run off of the steel even if it has been sitting in the sunshine for a couple of days. The paint sticks to the metal and it does not rust near as quickly when heated before painting. |

I don't think paint (or primer for that matter) sticks to stainless all that well anyway. I would leave it as is. ------------- '49 G, '54 WD45, '55 CA, '56 WD45D, '57 WD45, '58 D14, '59 D14, '60 D14, '61 D15D, '66 D15II, '66 D21II, '67 D17IV, '67 D17IVD, '67 190XTD, '73 620, '76 185, '77 175, '84 8030, '85 6080 |

If you really want paint to stick to your stainless, I'd sand blast it so it has a satin finish. Roughing it up gives the paint something to hang on to. ------------- "Any man who thinks he can be happy and prosperous by letting the government take care of him better take a closer look at the American Indian."

That moisture you are seeing may not be coming from the steel but from your torch, most gases contain moisture, especially natural gas and LP gas. Dusty ------------- 917 H, '48 G, '65 D-10 series III "Allis Express" |

| Toscani's got it right. If you must paint it, sandblast and then use an adhesion promoting primer (like XIM's Flash Bond http://www.ximbonder.com/products_detail.asp?id=63 - http://www.ximbonder.com/products_detail.asp?id=63 ) I had an awful time getting paint to stick to a stainless project at my day job, and this was the only thing that worked in the end. |

| We used to use the xim flash bond for hard to hold areas, works like a charm. Just not as cheap as other stuff. |
