Clear Coat Problems

[mentor2]

Hi all.

I'm having a bit of a problem.

I was helping my friend spray a small section of his car. The paint turned out great and blended perfectly to the old colour, but the clearcoat came out really bad. It came out looking like a golf ball. I was very particular in using wax and grease remover in the prep.

The same thing happened to a motorbike part I was spraying at the same time.

I am not using professional products, and don't mind if i shoot down orange peel as it is rather easy to fix, but I didn't expect it to turn out quite like this.

I have sanded the motorbike piece (blue) down to 1500grit, resprayed clear, then sanded down to 1500 again and it still is showing some dimples. I was thinking of doing the same to the car but but don't want to have to respray 3 or 4 times in order for it to be smooth.

Does anyone have any suggestions??

I'm using a preval setup and air dry.
50mL HiChem Super Clearcoat
25mL HiChem Medium Hardner
8mL HiChem Thinner

I'm wondering if I sand the car down as flat as I can and use the clear coat in a can, if that'll turn out okay. Would the can version adhere to the 2pack clear coat?

I appreciate all comments and criticism. I can't afford a full spray setup, and have found preval to work in the past, but am unsure why it is doing now what it is doing.

Thanks
Andrew
