Yes, did them myself.
First you have to wash and sand them a little so they are clean, don't have to be smooth becouse you want structure.
Then you degrease them and they are ready to paint, make sure its 20+ degrees outside.
When you spray the wrinkle coat at first it looks like normal paint.
The wrinkle/shrinking starts when you bake the parts for 25 min every layer in the oven at 125 degrees.
You whil see some result at 15 min baking.
The intake and little front cover are the best looking this got 4 layers, the covers got 3.
After 1 day drying the transformation is complete you can sand the ribs with 150 - 400 -1000 to polish.
I did al the parts with one spraycan, the coating is heat resitant.
Before you start, make sure youre wife is gone for 2 days...
