Step by Step Candy Paint job...
Ya I know this is way overdue, but I was hesitant on doing it because there are so many ways of doing a candy job............................. that and I honestly donāt think you can learn how to do it just by reading something........it really takes practice practice and practice. You should start with solid based then move up to metalics and pearls before candy. Trust me, if you can't lay down a uniform metalic job, you will not be able to do a candy job........not yet any way so practice.
Here it goes..........
Since you should already know how to do all the prep work, Iāll skip all that and start at the point were the car should be ready for paint.
The first thing to do is choose your base color and candy color. You can go with traditional silver or gold base, but the truth is that you can use any color base you want. Candy jobs are all about being creative customs, and the base color is the first step in getting creative.
TIP - if you are going with a silver base, just use HOKās silver sealer and skip the base, itās a very nice and sparkly silver metallic, but best off all youāll save time and money.
Once you have your base and candy colors picked, spray a test panel. Make sure you have full coverage with the base, and use even passes on the candy. Keep on applying coats until you reach the desired tone, remember the more coats of candy you put on the darker the color will be. Keep in mind the number of coats that was needed to get you're desired tone, this will give you an idea of how many coats of candy you will be putting on the outside of the care, but doesnāt mean it is an exact number. You're test panel will be an important guide in keeping your color both inside and outside uniform.
When doing a candy job it is always best to remove anything that will not be painted, as well as the doors, hood and trunk lid in order to do the jams. (you donāt have to, but itās better if you do)
If you didnāt gut your interior, make sure it is well masked off, the same with the engine bay.
You can save time if you hang, or rest the doors, hood and trunk lid were you can spray the under sides as you do the jams.
Again all your prep work should be done by now, so start by applying your sealer and base color
Once you have applied your base, mix in 4 oz of candy concentrate to 1 quart of pre-mixed ready to spray candy. This will cut the number of coats needed for full coverage in half. Though it will reduce the depth of the final appearance, itās important because less coats means less orange peel. So innless you plan on cutting and buffing your inner jams (some pro-show cars are done that way) make sure you donāt skip this step.
Now that you have the candy mixed for the jams......when spraying try to make straight even passes, I know there are lots of curves, cracks and grooves but do your best. Use your test panel to determine when you have reached your desired tone. Once that is achieved, spray 2 wet coats of clear and you're done with the trunk, hood, and door jams. If you had space in you're shop you may have been able to do the underside of the trunk, and hood, as well as the inside of the doors, if not, just do these the next day while your jams are curing.
Wait about 2 to 3 days later in order for the jams and doors to cure before reinstalling them. Make sure everything lines up properly.
wet sand any over spray that got on the body from doing the jams, and clean.
run masking tape along the edge of the inner jams to keep paint from misting into the cracks. 3Mās soft foam masking tape works best for this......Do the same with the trunk and hood.
Prep and clean the outside for paint.
Apply your sealer, and base.
Now youāre ready for the candy.
For you're fist coat of candy you are going to dilute it 25% by adding urethane clear to the candy (if using premix candy) So your first coat will be a 3 parts candy to 1 part clear mix. You may delute as much as 50% on your first coat to help you from starting out with blotches.
Adjust you're gun to your preference. Keep in mind that you will be shooting from around 8ā away from the surface, with at least an 8ā fan pattern. Here is were having a pro gun really comes in handy.
I find it easer to stay in straight even vertical lines if I start spraying from the bottom and work my way up. DO NOT FOLLOW THE CARāS BODYLINES. Make up your own āimaginaryā lines to follow that are leveled and straight. Keep an even pace when spraying, and move faster then you would on a normal bb/cc job.... Donāt jog or run across, it will be just a quick walk. This will give you more uniform light/medium coats. Always keep your gun steady, leveled, and even. Each pass will be overlapped by the next by 75%, and yes you will be walking the entire length of the car.
Once you have one side done, you may do the same to the other side, or move up to the roof, trunk and hood.
When doing the roof, trunk, and hood, start with the roof. You may need a long step stool that lets you spray from the rear to the front with out stopping. You could easily make one out of wood planks. Just like on the sides, keep your passes even and straight using the same speed too. Stop right BEFORE you get to the very middle. Do the same with the trunk and hood. Then switch sides. This time you will stop right AT the middle though.
That middle line is notorious for tiger striping or should I say stripe......many tend to get a darker stripe right down the middle because they move right up to it from one end, and do the same from the other giving it double the coats as the rest of the car. This is something that definitely needs to be avoided and kept an eye on as you continue with the rest of the coats. Moving right up to it from one side, but stoping right befor it from the other usualy provents this problem.
Now that the first coat is done, you will do the exact same thing with the up coming coats, only that the candy mix with be at normal strength with no clear added to dilute it. Keep your test panel handy and check it after each coat. You will know you have enough coats, when your car and test panel match in color. And since you used the same test panel to color match the jams, then your jams and outside should match as well. 5 to 6 coats is average for a candy job, but donāt be surprise to go up to 10
After you're last coat of candy, apply 3 coats of UV protective topcoat clear. You could use normal clear, but the UV protection will help your color last longer.
Wait a couple of days before coming back to block sand it with 600 and giving it āa flow coatā 1 or 2 more wet coats of clear...This will cut down on the orange peel dramatically and make it easer to cut and buff.
Well there you have it, I know I skipped allot of general details, but those are common sense things that you should already know about if you're planning on tackling a candy job. One more thing I will touch base on is the mixing of your own candy.
In the above step by step I was mostly referring to the use of premix urethane candy, but you can mix you're own candy using candy concentrates or toners mixed in urethane topcoat clear or intercoat clear........
If you do mix your candy using intercoat clear, I suggest PPGās DCU500(?) blending clear over HOKās intercoat clear, mainly because PPGās doesnāt have a build restriction were HOKās sagest not to build thereās past 4 coats.
Mixing your own candy using intercoat clear does make the whole job less expensive and easer to spray, since itās less likely of you having a run with intercoat clear -vs- urethane topcoat clear, Youāll get less orange peel too. Just make sure you mix it in the right amounts, People tend to over mix there candy and get full coverage in less coats, witch cuts down on your depth, and that defeats the purpose of using candy in the first place. If using candy concentrates itās usually 4 oz per 1 qrt of clear, about half that if using toners. But experiment with test panels to get your preferred mix.
For those of you who already have experience with candy jobs, feel free to add your comments or suggestions (I know there will be lots)
And for those of you who are planning on there first candy job......Good luck and donāt get discouraged, and once you have it down start adding flakes, patterns pearls, gold leaf, silver leaf, dollar bills, bugs........under, over or sandwiched in-between the candy.......YOUR IMAGINATION IS THE LIMIT!!
