Ramblings: Wrinkle Black Spray Paint Solves Front Spoiler Rock Chip Problems

When I added my fiberglass front spoiler to my 1974 AMC Javelin AMX, I decided I was going to do all the prep & paint work myself.  I sanded it down, cleaned it with POR 15 Marine Clean, spray two coats of high yield primer, Eastwood Flat Black spray paint and Eastwood Diamond Clear.  I followed all instructions to a T, letting everything cure and sanding between coats.  The results were great..for a while.  Then, after a few short weeks of daily highway driving, I noticed there were white spots all over my front spoiler.  Bugs and rocks were taking it's toll.  Hind site is 20/20...I should have taken it to a professional body shop and had it prepped, painted and cleared.  My budget didn't allow for that so I've had to occasionally go back and do touch ups.  However, it just doesn't look good or last. 

So, after a lot of research, I decided to try Harley Davidson wrinkle black spray paint.  It's extra heavy duty and is compatible with fiberglass (many other brands say that are not compatible with fiberglass on their instructions).  The Harley crowd says this is the most durable wrinkle black spray paint hands down...even though this stuff is really expensive, it's worth it to not have to keep doing touch ups or spend even more for professional finishing. 

Firs, I cleaned and sanded the front spoiler by hand.  Then, I applied 3-coats of wrinkle black spray paint over a 6-hour period (with no extra primer).  I let it cure between coats but didn't sand between them nor did I add any clear over the paint.   My preliminary results are excellent!  I've been driving everyday on the highway and down country roads with no chips yet.  Harley Davidson wrinkle black spray paint really works!
