Frame

What would be the negatives of powder coating the frame? (exclude Cost- cause it will cost me nothing just mediablasting it clean)

Positive- other than durability?

What about Powder coating clutch/break pedal?

Weighing options and would love to hear all sides on this?
 
...not nearly as likely to get chips. I had a frame powder coated about 20 years ago and was redoing the car last year. I washed most of the frame with soap and water and it looked like new again.
 
Are you planning on building a points car or a driver? I haven't tried touching up chips in powder coating, so I can't comment about that, but if you're doing a points car and will be wanting to touch things up to keep it looking it's best, you may wish to consider a paint. If you're going for a driver and not going to be concerned about the chips that happen, powder coating might let you have it done once and forget about it, because it is tough stuff. I've used powder coating on both cars and motorcycles and have been happy with both the quality of the finish (greatly depends on who does the powder coating) and the durability. Check for a sample of the company's work and know what your getting, because industrial powder coating is different than others.
 
I personally don't like powder coating, did it once. Had chips on the bottom of the frame and it started to rust beyond the initial chip point under the coating. It was a real pain to try to stop the spreading. Since then it's industrial epoxy paint, sand and blast.
 
Wuudie, I was a big fan of P.C. till I spoke to a friend about it. This guy is a painter, welder, sandblaster and a general jack of all trades. His advice was avoid P.C. like the plague. Moisture gets in underneath the coating and rusts away the metal like termites eating the beams in your house. You don't see it happening until it's too late. Go to a local boat yard and look at the condition of the powder coated pieces.
Go to Magnet Paint online and have a look at their 'Chassis Saver."

Jeeeeez, .....where does all this 'stuff' come from??

First off, we can touch up powderpainted surfaces so Yes it can be done. Second, I have had several Model A's in fine-point judging that received no deduction from having a powder painted frame so you can do that too. I actually had one in French Lick with a painted frame get a deduction because the judges thought it was powdercoated. Heck, even an original frame did not have laquer, enamel, or urethane paint on it from the factory so why is it wrong for powder paint but OK for enamel or urethane??

Now here is the low-down on P/C vs. sprayed Paint. The benefit for the sprayer of powder paint is, unlike in the case of 2K paint there is no VOC or Iso's to worry about harming your health. The other thing about P/C is as soon as we coat the item and it has cooled (30 minutes +/-), it is ready to be installed whereas catalyzed paint needs curing time. Now to be fair to all sides here, if you use a cheap spray paint OR a cheap powder paint, it won't last with either type of product. And, common sense tells us that if you spray 2K urethane over a rusted, improperly prepared piece of metal, you are likely going to have a failure just like you will if you do the same with powder paint. I feel fairly certain that for every failure someone can name in powdercoating, someone else can cite an example of failure with sprayed paint!!

I really like powder coating wheels ... but a frame? Just get it sandblasted, use a good primer, and top-coat it with a high quality urethane. You will have basically the same thing without all the expense of pc.
 
I had a motorcycle with powder coated handlebars ad it was a nightmare trying to get a ground through them enough to run the controls, I'm not sure how much trouble it would be to clean every little mount point to get good continuity
 
Why stop at the frame?

Not nearly as easy as paint to fix chips.

I've had good success fixing chips on my powdercoat.
Aerosol-can lacquer works well.
Simply spray a little into the cap, then build up the chip with a tiny brush. Next day level it with a pumice stone or microfine, and cut polish to your desired level of gloss.
It can just as easily be feathered out, spotprimed and dusted in with spray paint.
Powdercoat will wetsand like well cured paint
(no kidding, that's what it is) and it LOVES to be cutpolished.
I keep hearing about different qualities of the stuff...maybe SOME powdercoat isn't so easy to touchup afterall? I'll bet bad preperation plays a key...just as it does under conventional paint.
All of my frame and running gear was nickel slag blasted and rust pits filled with JB weld. It was washed & dried with wax & grease solvent before hitting the powder room.
...I musta got lucky because this stuff is almost impossible to chip. :)
 
I had a powdered coated frame on an ERA Cobra for 14 years. All I ever did was whipe it down with Prep-sol every now and then and it always looked like new. Scraped bottom once and touched it up with Rustolum spray and could not tell the difference.
 
Why stop at the frame?


This is exactly what I was thinking on mine.

Breaking the whole thing down P/Cing frame and components

I'm doing a driver- the only judging I'll get is from everyone who "knows it all" and walks by the car telling me "Model A's only had wooden wheels and were only painted in black"

Maybe the next one will be FP Judging
