Sunday, August 19, 2007 5:34 AM
I had some body work done on my car a while ago. when i went to go pick up my car it diddent look bad. But now about a month later it looks like the orange peal is getting worse. There is even some parts that looks like it pitting. This whole experince with this body shop was horrible. The window leaked after it was fixed, my car is a ls sport and they put the non ls sport bumper on my car (no lip), frogot the pinstripe, door did not shut right. body filler job was done half ass. Well anyways if your ever in north florida dont ever get any body work done at preston hood. Anyways now that i got way off topic can someone just tell me what causes orange peal?

nevermind i was seaching google and noting came up for orange peal, then i went to yahoo and typed it in and yahoo sugested "peel" i found what i was looking for




just incase you dont/want to know

CAUSE

1. Under reduction and/or air pressure too low.
2. Thinner/reducer evaporates too fast for spray conditions.
3. Excessive film thickness or piling on of heavy wet coats.
4. Improper spray gun set-up.
5. Improper painting technique.

REPAIR

1. Compound or polish to reduce surface texture.
2. Or, sand smooth with 1200 or finer grit sandpaper, compound and polish to restore gloss.
3. Or, sand smooth and refinish.

PREVENTION

1. Use proper reduction ratio and spray at recommended air pressure.
2. Select recommended thinner/reducer based on temperature, humidity, air movement, and size of repair.
3. Avoid heavy coats and excessive film thickness.
4. Use recommended spray gun, fluid tip and air cap for the material being sprayed. Always adjust the gun for best atomization and balanced spray pattern before paint application.
5. During paint application, hold the gun perpendicular and parallel to the surface. Adjust speed of pass, pattern overlap, and distance from the panel to achieve the desired appearance.

and what they don't' tell you there is that orange peel is completely normal. Go to a new car dealership, every car has orange peel... why? Because it''s normal.

The factors listed can contribute to EXCESSIVE orange peel, but a certain amount is completely normal... and unavoidable. Unless you have some sort of weather station in the paintbooth that calculates the temperature and humidity and such in the air and automatically adjusts the mixture of not only the paint you''re spraying, but the paint you''ve already sprayed... etc. Cars at production plants are sprayed by machines, and if a machine ccan''t get it right, a human certainly will not.

With that said, I can''t understand why your paint would be getting worse a month later. But if the shop did crappy work to begin with, I would say that''s definately on them. Did you check to see if they guaranteed their work before you went there? Never go to a shop that won't guarantee their work.
