Not sure what they charge for blasting in your area but here it's not cheap - $75/hour and up.

Local powdercoater will do blasting for me, he has serious equipment and prob could have done in 3 or 4 hours what it took me 18 hours to do (no kidding) I'd gladly paid him 350 bucks to bail me out of that weekend! :D I hate to say it, but there was some MCU involved.:rolleyes:
SPI epoxy saved me, I'll never look back.
 
Good thread, was going to start my own with a media blasting question but found this one so, here's my question. I have 99.9% of the paint removed from my trunk lid. I would like to remove that 1% along the edge of the rolled panel lip. I have a 30 gallon media blaster and a quart size spot blaster. The media I have in the garage is a medium glass bead by Clean Bite, will this work and provide a good adhesion for spi epoxy?

I dont see much need to dig that out, you can with a knife or something. Unless you are going to separate the skin from the underside, (like the guy in the other thread) you will have rust all along that inside mating surface. Thats where you pour some epoxy inside and turn the lid clockwise or counter clockwise to try to get to the inside of that surface.

Thank you, so is the glass bead material I posted okay to use for small area spot blasting when using spi epoxy?

I don't think that is glass bead, I think it is crushed glass. Glass bead does not leave adequate "tooth" for refinishing, so it's much better if it is indeed crushed glass.

Good catch........ my error. It is indeed crushed glass.
 
Plus it's cheap. On sale now at Northern Tools for 8.99 for a 50 lb bag. I got 20 bags at Northern awhile back for 7.99 each, plus I had a coupon which knocked another $20 off the total.
