Researching: Spray Bomb Painting : Proper Techniques.

[02Zetechse]

Thankyou Norcal, That sounds very true about being overused . I am planning a OD Green Flat/Gloss (undecided) with Satin roof ,hood and Trunk. In every forum i read they say with good prep a rattle can will still last a long time .

I have a bumper and hood I need to paint. Would it be terribly unwise to try painting it myself until I can afford to get it professionally done?

IMO, Do your research before you Try to paint anything by yourself. There are a few companies that offer automotive spray paints. Try Alsa Corps "Killer Cans" they are a can with hardener in it . If you chose to Go the Cheap Route Brands I recommend are Rustoleum and Valspar . use dish Soap and water to wipe down the hood to get the dirt and wax off . you want to Scuff your clear coat using approx 200 Grit Wet/Dry sand paper. Wipe it down again with mineral spirits or paint thinner and allow to dry. Spray a Light Coat of high build primer ( IIRC: Rustoleum brand) It will fill in the Scuff Marks. Let the paint dry several hours. Use 400-600 grit to sand the primer coat smooth .

Wash the hood down thoroughly to get the dirt and sanding dust off. Spray a several more light coats and let dry . You should not cover the old paint completely in one coat ,If so you are spraying the paint too thick . try moving the can further away or move more quickly across the hood. After those coats dry wet sand using 1000+ grit to make the surface glassy smooth as rattle cans tend to show every scratch /scuff below it. If you are OCD I recommend going all the way to 2000 grit paper in your sanding. Now to the color coat, A color coat will likely have unevenness to it if you do not have enough coats on it. Depending on the color and brand of paint you may need more or less coats. there will be over spray from the can of paint. Something I do when using aerosol paints is use a box fan to suck the air from my workspace to keep the paint cloud from settling on my painted piece.

For the bumper I would use a adhesion promoter to make the paint stick to the plastic .

I have read that you can claybar the piece to get the overspray off to make the hood smooth.

Anytime you get something professionally painted they will charge you a little more for stripping a spray painted piece.

What if I get black hood and black bumper and want to paint it Infra Red? Do I have to take off the black paint first?

The paint in a rattle can is no differant than paint in brush form. IDK why so many people think that paint in a spray can is cheaper paint.

Depend on what you want for an out come. Ive used rattle cans on my trunk lid and door. I took my time and finished it with rubbing compound, you cant tell that I used a spray can.

I wouldnt, just use gray primer first.

I have to disagree with Norcal on using grey primer to go from black to red .Although your results will prolly be unnoticeably different I would use the Red Oxide Primer. Its a red/brown primer . Either way its done will work perfectly fine. The red paint may cover better on the Red Oxide Primer.

The reason you want to use a differant color primer, is so when paint the finish coat on, if you cant see the primer, you know youve put enough paint on.

Hi end auto painters used to use red oxide primer, under yellow, blue, black. Just so they knew they had put an even full coat on the car.

No problem. Please go ahead and do so.

Kinda of a side bar, but I seen paint specs for bridges that say red for the 1st coat, yellow for 2nd coat, and blue for the 3rd. Just so the job inspector knows that enough paint had been put on the bridge.
