Powdered coat is hard to grind off if you have to make chassis repairs and matching up the colors sometimes can be a problem. I see alot powdered coated and about as many painted. Pros and cons with both. Maybe this will help you.

Paint, powder is hard to fix after a repair.
It cost more to have done. Then if you do need to weld something you try to grind or wire brush the powder off, thats a pain, then you go to weld, its very hard to get a good weld unless you can get ALL of it out, which is about impossible sometimes.
I stick to piant. easier to strip, and easier to fix.
I have heard of drag cars just being "greesed" to keep rust off that way they can find cracks easy.(we painted a couple rail cars and they were talking about them).

With powder coating when you crack a weld the coating doesn't crack so it hides the crack and like it was said before it's a pain when you make repairs. You can save a lot of weight without paint or powder coating. With powder coating it does look good till you make a repair. We just use paint for the ease of repair.

We have had modifieds for almost ten years and have had 7 painted and 2 powdered. The 7 were Dirtworks and the paint fell off them so fast, that when you wash them you would have to wash by hand to keep the paint on. So we tried to paint them ourselves with primer and taking our time to get the best lasting finish possible and it still came off. When switched to Harris we had them powdercoat the chassis and have or will not ever switch back to paint. If you care anything about how your equipment looks, powder is the only way to go. If you really think weight is an issue leave it bare. And then just duct tape numbers on it and save your money. Cuz there is no sense in wastin' money on a nice letter job when it's gonna look like s@#$ anyway.

I powdercoat the body, interior,bumpers, brackets, fuel cell can really, just about anything that unbolts. But I paint the chassis.
I powdercoated my first few chassis's and it does make it difficult to repair. But the stuff you are going to throw out rather then repair, Powdercoat it and it will look good for a long time.
Just make sure your powdercoat guy sells you the right powder, some powder does not stand up well to sunlight and will fade quickly.

At the track we run it has a lot of rock in it and it doesn't mater if its powder coated or painted they all chip. As for washing we never have a problem with the paint coming off and we use a 2200psi power washer every week.

I am thinking about taking steel wool to one, and then clearing it over metal. Use a good self etching clear, cleaning the metal really good before hand. It should be fine.

Should look trick to, bear metal frame look. Seen a midget done this way, guy built with bi-plane tube, really neat.

That or flat black powder coat.

Use a nice epoxy primer/paint, Almost as tough as powder coat. The crack thing with the powder coat is very true it does do a good job of hiding them. That powder cost almost twice as much to remove, both money and time.

I use paint from the tractor supply store. You can brush it or shoot it. It goes on thick and doesn't chip easily. Cost me $15 a quart but two quart's will cover with a half left for repairs.

I do some powdercoating myself. I do alot of the bolt on parts, the wheels(if needed), hubs, Other small things you can think off. I paint the front end parts sometimes like metric spindles, centerlinks, tierod ends, then when the paint chips off you can see a flex point easier.
On the frames, Stated above the paint falls off. I dont know who is doing the cars, but mine we sandblast and paint, usually no primer even and it stays on great. I do have a professional painter(friend) do the paint on it, we blast it, then run over it with sandpaper quickly. The weld area's that are new we blast around them extra close, then we take a hand drill with a wire brush and get them extra clean. Next step is to rub the frame down with thinner, and more and more. Go over every part till the rags stay pretty clean. Then let it air dry for a few min. Taking tac rags over it a few times to take any other specs of rag or towels off of it. Then mix up the paint and shoot it, most the time with no primer. We use a single stage. The first time we skipped some stuff and paint fell off some, now we stick to cleaning, and paint does not come off. We use one coat and let it sit some, then a light coat. Finally we pull the frame outside(once dry to the touch) and check it over in the light, using a touch up gun to finish it off.(you always miss spots it seems).
A common misconception with powder coat is that it is stronger. Some poweder coat is stronger, some is actually weaker than a good paint job, usually the wilder the color the weaker the powder. It depends on what the powder is actually made of(different types of materials).
Powder also concels cracks which should be a worry.
If you do have it powdered it is harder to match the color when needed, harder to work on, and a sandblasters dream...they will hate you after. Getting parts to chip off is not that hard, but getting the little specs left over can be a real pain.

My cars look good, there usually is no argue on it, we paint the frames/and body all of it is painted. So powder is not the only way to go if you want to look good.

Finally to krom.
We had an old fridge from teh 50's in our shop, kasey(the friend that is a painter) decided he did not like the white look. So he took it. Took a grinder with like a flap wheel(cannot remember the name, but it is plastic disc and has little flaps leaned over) and went up and down all over it, taking ALL the paint off, then smoothing it till it had a uniform strip patern made by the grinder, from top to bottom. Next the guy took a regular grinder wheel and ground a flame design to about half way up on it. Then clear coated it all. It looked F... COOL. The clear and look stayed on for about 2.5 years before a slight bit of rust started to form on the surface in a few spots down on the bottom area. I will try to find a pic but that was along time back when we had it, and it stopped working so gave it away. But krom that would look cool.

Driver likes powdercoating ,me I like the painting with Rustoluem. A clean chassis the rustoluem sticks like gule and never came off until grinded off, plus it left a nice smooth surface. I think the driver did not like the paint because he got in in his hair when painting the chassis.......

We wear the full body white thin plastic paint suits, but still get paint on us.

An easier way to get powder coat off is to use Aircraft paint striper. It will soften the powder coat where you can just s****e it off with a puddy knife.

Paint it my man We've never used poweder coat, but painting makes more sense to me. We used about $15 of spray paint from the local hardware store and noone can tell the differance between that and something shot out of a air gun. paint it lighter, easier to work with, and if it ever needs a touch up we just give it a little shot with the spray paint. We've not
had any problems with paint chipping off unless we got into another car.

I prefer powder. It is tougher by all means, unless the coater does a terrible job. Paint if done right is just as good as powder and just as hard to get off. Any grinder with a wire wheel will peel powder coat right off.

You can match almost any color of powder now adays with paint.

But, for me it's easier to drop it off and let them do all the prep work and shoot it for nothing

Well my biggest problem with Powder coat is that if something happens at the track who has the time to grind and chip away powder coat if you gotta weld in a hurry?

Its fine if nothing ever happens to you and your not worried about just putting the car up on the trailer for the night, but I like to get my driver out on track every chance and time is everything. That is my main reason for not using powder coat.

I've never heard of someone not making a race because of the powder coating?

It takes the same time just more effort to get it off. I'll tell you that chipping it off isn't a good Idea either. Grind it off, any grinder will go right through it. I prefer to use a real gritty flapper wheel, it'll eat right through it.

Last year we put 2 tail sections on a Hoffman car. The Chassis was white, we were able to put the tail on in a night, and have it painted to match the next night.

We've had painted chassis that were absolutely beautiful. We had a Dirtworks DW-8 Painted White at Dirtworks and it was an absolute mess. Chipped almost nightly. If you really care about how your chassis looks, and plan on keeping it more than a year then Powder Coat it. Anybody that sandblasts will be able to remove it easily. Some powdercoating shops have a bake off oven that they can bake it off and start fresh.
