This is easiest done by spraying another medium coat on lightly re-wetting any spots where needed (do this immediately after your second coat or it will create dry spots). The second coat, spray it to look like you want it to look. WARNING: Clear coat is very easy to run so use medium wet coats. The clear should be mostly glossy on your first coat, but not overly glossy. Now spray the face of the bumper cover using a 50% over lap pattern and staying about 6-8 inches away from the panel. Load your spray gun with the clear coat and spray around all the edges. In this instance, we are going to use two coats of clear coat. Your product data sheet should also tell you how many coats of clear are recommended. The ratio will vary depending on brand, but be as precise as possible with your mixture. The clear coat mixture should consist of clear coat, hardener, and reducer. Make sure your basecoat is thoroughly dry and mix the clear coat according to your product data sheet. Be sure to read the product data sheet for *flash times in between coats, but it should be approximately 5 minutes depending on temperature and air flow.Ĭlean out your spray gun with lacquer thinner. Basecoat should cover in 2-3 coats with the exception of reds, yellows, oranges, and some silvers which tend to struggle to gain coverage. (this means that there is not a certain number of coats to finish the basecoat but rather the paint should look consistent across the entire part and not look blotchy, or modeled as it is called more commonly). The basecoat phase is finished to coverage. Start by spraying the edges of the part then do a 50% overlap across the face staying about 8 inches away. Sometimes the basecoat also requires a hardener. Depending on the brand and grade of the basecoat, the mixture should consist of the color and reducer. Mix the basecoat according to the product data sheets. The sealer should be flashed off by this point and ready to put your color matched basecoat on the part. Clean your spray gun out thoroughly with lacquer thinner. The product data sheet should give a *Flash or *Recoat time (this should be about 5 to 10 minutes). Now go across the face of the bumper cover using a 50% overlap (do not spray this product heavy to avoid any runs in the sealer). Once the spray gun is adjusted, spray around all the edges of the part staying about 8 inches away from the panel. The pattern should be consistent and not heavy at the ends of the pattern or in the middle. Now adjust the fan pattern of the gun to a 6-inch oval. Then set your air pressure at the gun to 21lbs. With the sealer loaded into your spray gun, adjust the fluid knob about 1.5- 2 turns out. Mix your sealer exactly for optimal results (this is found in the product data sheet). Using the *product data sheet, your paint brand will give the proper mixing ratios and application notes. If you see any spots of concern, try using the tack rag to clean the spot. Your part should be prepped, cleaned, and tacked off at this point. This problem is fixed by reapplying your basecaot with a consistent pattern and not sprayed too heavy. The other way this happens is when your pattern is not correct for your spray gun, the basecoat is put on too heavy, and/or the metallics in the basecoat do not sit correctly. This is not true modeling, but can give the appearance of modeling. The first is your color has not quite covered the panel yet. * Modeling: This is an appearance defect that can happen in two ways.* Recoat Time: Time you must wait until the paint is cured enough to spray the next material on your panel.* Flash Time: Time you must wait between applying coats of the same paint.
