orange peel

Hey, im not sure if this is the right place to post this thread. I started airbrushing a year ago, and recently got a hvlp gravity feed spray gun from DeVilbiss. After i design the motorbike piece and go to put the lacquer it gives an orange peel texture.

I have tryed ways to prevent it like, increasing air pressure, playing with the fluid flow, gun distance/speed. If you got any other ideas please post up. Im going crazy with it, ive tested different ways on scrap car pieces before i do it on the bike but same result all the time. Evil or Very Mad

Wait for it to bake off then,
You need to use 1500 on a disc,
or 2000 wet and dry paper, use a flat surface like a block or DA, flat it all off till it starts looking matt, be careful of edges they burn through very easy, then work at it upwards starting at a harsh grade polish upwards.

The temp in my garage is good, so it cant be that. I was thinking of thinning the lacquer but theres a label on the bottle "no thinner", so i scraped that idea. Im also going to start getting parts for designs from people to do and cant give them a finished piece with the lacquer looking like that. Im going to try and use a wet, soapy 1500 on a disk and see how it goes, ill try posting pics of end results.

Dont do a wet soapy 1500 disc it will clog in seconds!
where i used to work we used to polish new sprays using
1500 disc on DA till matt.
Trizact disc with water on da,
then start with the compounds.

eek, ok scrap that idea too. i wont even bother using a wet and soapy 1500.

Ive always been taught to use the disc 1500 on the DA till matt as said, then use a 3m trizact disc which (iirc the grade these actually achieve is 3000) with water, then start on poishing, dont bodge it, will make it even worse than it already sounds like it is.

The orange peel effect is usually caused by

1. Using the wrong mix of paints, eg cellulose primer with acrylic top coat, or maybe a acylic primer with a cellulose top coat.
Make sure you not mixing your paints.

2. Water. if you still have water residue from wet and drying and then apply the laquer/to coat it'll fuck up, degreese it, let it dry properlly the laquer/topcoat it.
