sandblasting front lip ??

ok so i have a greddy front lip that was white and had rock chips

i have sanded for hours on end and still cant get all the chips out ( also the greddy letters are hard to get into )

i wanted to know if you can sand blast plastic ? id like to have all the old paint gone and start from scratch !

or if any one has any better ideas ??

Maybe someone has a better idea.... but if you're going to paint the entire thing, why not just use paint thinner/remover?

Re: sandblasting front lip ??

depending on the scratches, you could use sandable primer and just do multiple coats. little bonding agent before the primer. you could also get a little more aggresive. use a coarser sandpaper and try a palm sander. rotary tools also have some handy bits or, i just used a detail sander with 100 grit on a lip yesterday. turned out well after the paper wore down a bit. didnt have to go to a finer grit as you want some coarseness for the primer.

Re: sandblasting front lip ??

there is paint stripper, ive never used it one frp, or urethane though. i dont know if it would end well. i can see sandblasting working well on urethane because depth isnt really an issue. with the replicas made of frp. you get through the plastic into the fiberglass and it might turn out like crap in a hurry. probably not telling you something you dont know though.

You could soda blast it. Won't harm the lip, but will strip the paint off.

You can buy a cheap-o kit from harbor freight if you're just doing one lip...
