Re: Powder Coat vs Paint

Dear Cliff and the List: Beware of powder coating, especially in wet climates. It forms a hard shell which can, and will, crack especially on parts that flex or strain. Water then enters these tiny cracks and the parts rust inside the powder coated shell usually without any outward sign until the part breaks. Powder coating wire wheels may seem like a good idea, but in the long run it isn't. One takes ones life in the powder coater's hands. We suggest you check this out for yourself. We also suggest you stick with paint for any chassis parts or any part that may be exposed to flexing and moisture. Kindest regards, Alan & Victoria Campbell TA 1282 & other prewar things British

Alan a very interesting observation do you have some first hand examples? I was thinking of coating some of the Morris suspension. Joe

Dear Joe: If memory serves, the news on powder coating came to us from Dayton Wire Wheel, after we shipped a set of wheels to them that had been powder coated. Dayton told us they have seen serious rust underneath powder coated parts that looked just fine. You might wish to inquire of them and British Wire Wheel as well. Since then, we have opted for paint in light of their recommendation. Besides, it makes sense. As we understand it, both paint and powder coat form mechanical, not chemical, bonds. Powder coating goes one step further and forms a hard shell. If paint cracks, moisture gets underneath and corrosion occurs, the cracked bits tend to flake off whereas the powder coated hard shell will tend to stay intact thus hiding corrosion underneath. Powder coating is popular because it is less expensive than a quality paint job, forms a hard, durable and good looking finish and is easier to maintain. Unfortunately it appears that it can hide corrosion in a way paint doesn't. As we said earlier, check it out before proceeding. We are not the experts on this, just passing along information that may be of value to others on the list. Kindest regards, Alan & Victoria Campbell

Well now, I can't speak for anyone else's experience, so I won't, but I've personally used powder coating on wheels and such for over twenty years, in extreme conditions and with problem-free results. I will continue to do so. 'Course, anyone else can do as they please. Gee, I wonder why it's so widely accepted in industrial usage, it's more expensive than painting.

Let me point out to you all that while powder has its' place, there are some places that you really don't want to use it. With racing car suspensions, we noticed that powdered parts bolted together under high stress would tend to make the powder "flow", thus loosening some of the fasteners. Looks great on show cars, though. Too bad MG didn't have it available when the cars were new............. Best, Ray McCrary "Speed is Life; of course Luck and Altitude are helpful, too."

If you need powder coating remover it must be baked off. American Dry stripping in Bridgeport, Ct. can do this. They have the proper equipment. This is not an ad, just a statment of fact from a customer. Bob TC4946

Better stick to...ebay, or whatever you do. In industrial applications it is not more expensive than paint. I have been involved in high tech manufacturing for some time. Powder coat only goes where you want it, paint goes everywhere, even with robotic painters. Further, any excess can be collected and reused in the next run. Overspray on paint has to be collected, treated and the sludge disposed of in special dump sites. The costs of setting up a sophisticated 7 step paint line far exceed those of powdercoating. Finally, it requires less sophisticated labor to get a quality finish. For industrial, total cost considered, go powdercoat, IF you can get it in the correct color and it is suitable for the application. -----Original Message----- From: mrbadger [mailto:mrbadger@home.com] Sent: Sunday, April 29, 2001 6:09 PM To: mg-tabc@yahoogroups.com Subject: Re: [mg-tabc] Re: Powder Coat vs Paint Well now, I can't speak for anyone else's experience, so I won't, but I've personally used powder coating on wheels and such for over twenty years, in extreme conditions and with problem-free results.
