How do you make a fiberglass bumper shine after repainting in acrylic?

I repainted my fiberglass bumper and now the surface has loads of small bumps and it hardly shines at all. My reflection is just a blur. I used acrylic spray paint with an acrylic top coat.





How do I make it give a good shine and how can I make the surface completely smooth?





Thanks.|||Sometimes it takes several tries to get it right.It may be a good idea to watersand it smooth again with 800 grit then respray it.In the body shop we take pains to get the base coat perfect then wet down the top coat with clear.|||http://www.4wheelplay.co.uk/simoniz-back鈥?/a>
