Do I have enough paint?

Royce Brown · Sep 5, 2019

I'm getting ready to spray my 69 Coronet with a HoK system. I currently have:

1 gal primer (4:1)
1 qt Hardener
1 gal Orion Silver max base (2:1)
1.5 gal Apple Red Kandy (2:1)
1 gal Clear (3:1:1)
1 qt catalyst
1 gal reducer

I am planning on also buying 1 more pint of catalyst and 1 more gallon of reducer. I'm not doing the engine bay, interior, underneath or trunk area. I was only planning on doing the exterior and maybe door jambs. I was planning on 2-3 coats of silver and 5-6 coats of the candy. The candy is what I'm concerned with. It requires a 75% overlap and this is a big car. Has anyone else used this system and do you think I have enough paint?

Well, first off if your spraying this at home the catalyst contains isocyanates. Real bad stuff. Even fresh cartridges will not protect you 100% it also absorbs thru skin and eyes. Anyway, You may need more primer. Only focus on the primer, bondo and block sanding first. If its 2k primer that contains iso's too. Anyway, I've seen people do it with that amount but you may need more clear.

what does the chart for your brand of paint say?

mine is 8-1-2 meaning 8 parts paint, 1 part hardener and 2 parts reducer.

off the bat it looks like you got WAY too much hardener

I'm using the House of Kolor factory pack KBC11. The chart for the paint does not specify hardener. The hardener is for the primer which is an epoxy. The primer is 4 to 1. The paint is 2 to 1 with 2 parts paint and 1 part reducer.

Ok, I went back over the safety sheets and the primer is epoxy with no mention of isocyanates. The base color and candy do not mention them either. You are correct about the catalyst. That does have diisocyanate listed. I was planning to do primer/filler/block sanding until my arms fall off this weekend and maybe next weekend. I was going to do base and clear later this month. The plan for base and clear was to use the cartridge style mask, gloves, paint suit, goggles, sock, and a positive pressure setup. I have time so I can look into a better option for respiration protection. I'm assuming that a supplied air system is ideal but expensive. I'm open to suggestions.

Hi,

The mistake so many people make is with mixing and cleanup, you need protection. With a good respirator and being covered you’re pretty safe. With the isocyanate , prolonged exposure is where the problem starts. The VOCs are no picnic either.
As far as paint goes, calculate the area and check with the vendor, candy does not require much film thickness, just even/overlap

tak419 · Sep 5, 2019

If I figured things correctly you're short on the reducer. The base and the candy will take over 1 gallon and then you also need reducer for the clear. You need to get another gallon of reducer. As for spraying, wear a good respirator and hood to keep your hair from getting paint in it and don't worry about it. You don't spray every day for a living and a good respirator will keep you safe. According to California nothing is safe. Plastic bottles, food, water, air, everything gives you cancer. One time probably isn't gonna kill you. I know guys that sprayed lacquer for years and are healthy as hell yet my sister who's 53 and lived a very healthy life, didn't drink, never smoke and in great health is fighting ovarian cancer. Luck of the draw bud. Paint your car and enjoy life before it's over.

Did a bunch of internet searching and it seems like every thread has half the group saying isocyanates can hurt you even in small doses and filter masks do nothing to stop it. The other half say you are perfectly fine and it's only a problem after long term exposure. I'm playing it safe and bought a supplied air system. I'll hock it on fleabay when I'm done. Got the extra gallon of reducer as well. Thanks for the input. If I'm posted pictures later this month then you know it turned out well!

There is a short list of chemicals that a respirator can not block,
The isocyanate and good old methylene chloride (paint stripper) are two that I know of. You can’t go wrong with a fresh air system. Adequate ventilation is the most important.
Which air system did you get??

I a m glad you are getting a fresh air system. Let us know what you find and how well it works please. Here is the problem, some people like me, are way overly sensitive to some chemicals, especially the bad stuff in auto paint. It can kill people quick. Some people like me it can make you sick even with a good respirator , body suit, and trying to see thru goggle to paint I have tried it but I can't do it. I know I need a fresh air system!

Yeah Epoxy is mean as hell too! ha ha I was painting some quarters with it once and took my mask off before it was evacuated whooo! I have extreme respect for epoxy too! I guess the main thing besides your protection with painting at home is to keep people away you can mess them up pretty bad.

Is the ‘primer’ your sealer coat? What color is it?

I think your short .5 gallon on color, candy and clear. You might even need another gallon of clear. You’ll have to crank up the volume when you shoot clear, you lose a lot more vs base coat. Your reducers and catalyst is easy to figure with mix ratios.

When your painting you can’t stop for a week and get more supplies. Clear you can do more later but not color coats. Your window is hours and not days to get clear on. Silver is a fairly transparent color. You should do a spray out and see how many coats it takes to cover.

I ordered small 8oz cans just to do spray outs and I still have a few weeks before I'm ready to spray so I can play around. I'm going to do another spray out later today. I'm going to stagger my test panel so I can see what 4 vs 5 and 6 coats looks like side by side. When I did my initial spray out 3 coats of silver seemed to cover very well. I feel like I could get away with 2. The candy looked great after 5 coats. I was only planning on doing 2 coats of clear the day I spray color. Then I'm going to sand out trash and put a couple heavy coats on later. It seems that I will need another gallon of clear. Now for the color. Is 1.5 gallons sprayable silver cutting it too close for 3 coats? Is 2.25 gallons ready to spray candy cutting it close for 5 coats?

I went with the breath cool full face mask. That one and the hobby air were both very reasonable. The breath cool had better reviews.

Thanks for the info. Since the stuff can be absorbed thru your eyes, I bet the full mask is worth it. I have tried googles but they fog up/

This is very interesting since my car is in paint prison, I already pay for one gallon of paint and one gallon of clear, the reducers, the catalist, and all the stuff needed is what am about to pay, I dont want to spend the money i got for the car in other things... like my wife.

It's always best to 'err' on the safe side! And if you have sinus problems or allergies, the better your protective equipment, the better off you are.

Did you already jammed the car? Engine bay? Back sides of the panels, under hood?

I will be be doing that with another paint system. This candy is just for the exterior panels.

Do I have enough paint?
