I used a paint stripper and then cleaned the VC. I tried spray painting the VC with a high temp spray paint but each time I tried I got the paint to bubble and wrinkle as it was drying. What am I doing wrong? The same thing happened when I tried to paint the plastic spark plug cover...

 

single stage spray paint..?

did u lightly sand it, or wipe it down with cleaner before hand..?

i use etching primer on any straight metal parts, before painting them. Not sure if the high temp needs to sprayed straight to metal or not, but thats how i like to do it.

 

You need to wetsand it a bit 400-600 grit.

You need to find high temp primer as well.

I used high temp primer on mine and then spray regular satin krylon and no issues with flaking or bubbling even under operating temperature.

 

Yeah, I also used primer and it seemed ok but when I sprayed the color coat it bubbles as it was drying up.

 

How many layers did you do?
It seems like you are spraying too much on one spot.

 

I tried flashing with 15-20 minutes apart.

 

Unclean nozzle?
Are you using a rattle can?

 

Yup, can I bought at Autozone.

 

ok, there is a few things that could have gone wrong.

did you neutralize the paint stripper after the paint started coming off ? (rinse with alot of water)
sanding grit depends on if your using primer surfacer. if using surfacer 120-180 grit if not 320-400.

clean with wax and grease remover. paint will seperate if surface is dirty with grease or sylicone type chemicals.

 

I cleaned it with water and brake cleaner. I am thinking the brake cleaner was probably a bad idea. I will try with the sandpaper and see how that goes, same for the plastic cover? I appreciate your advice.

 

Yep. Toluene and Acetone in brake cleaner do not like paint.

 

no prob
