I stripped the frame and its ready for blasting. does anyone have any feed back on the type of media I should use. I plan on getting the frame powder coated and my local blaster leaves the frame rough will the powdercoating fill in the rough spots that the blasting leaves behind

It will be pretty smooth with the powder coat, but any pock marks, deeper scratches, divits will be visible under the powder coat.

If you want it right, sand blast it with silica sand.

You will need protection from the silica sand dust getting into your lungs if you sand blast it yourself. So you should rent or borrow or buy a supplied air setup to do it, although a respirator will help it won't give you the protection supplied air will.

I'll put some pictures up and some ideas on how to do one of these frames.

Heres the how to do it.

HOW I PAINTED THIS CHASSIS




Keep your floor, walls, airlines etc. clean and dust free.

Don't have any WD-40 silicone, carwax, carwax rags, or bug spray even in the building.

Don't start up any car, bikes, lawnmowers, or weedeaters in the building.

If you even think something is greasy or doesn't look clean, then use a little
acryliclean but don't soak it just clean it lightly.

I'm not talking wax and grease remover its ppg acryliclean.

Sandblast
36 grit on pock marks and gouges
body filler
re-sand 180 grit on pock mark and gouge area
two good coats of z-chrome sprayable body filler over everything
sand with 180 grit
re-sand with red scotchbrite, works better in tight areas
two coats of epoxy primer
Anyway, that's the way you do it.

Now get a spray gun with a big nozzle, wet the floor down and spray it
with z-chrome sprayable body filler with hardener.
Get a product sheet with it and any thing else you use on the frame, make sure
you do what the product sheet says.

Z-chrome is a sealer and rust-inhibitor part #20215

Let it get good and dry then sand it, use your good judgment on the grade of
sandpaper, but remember the last sanding step will be with red scotchbrite so
when your done you don't want any scratches deeper then the scotchbrite will take
out.

After you sand a while, you will see some bare metal, and when you get done most
of the z-chrome will be on the floor but still quite a bit on the frame.

Now clean up the area and blow the frame off quite a few times, reclean the floor
and walls blow the frame off a couple more times.

You will need a siphonfeed gun to spray it because the hi-vol cup will get in your way.

Now you need to hang the frame up so its about 4' high, that way you can reach
the top and get on your knees to do the under side.

I made special hangers to support it inside the body mount holes so nothing touches
the frame, these jigs are on the website.

You're going to need a really good respirator or supplied air when you spray it
because you'll be in there a long time to get all those side rails and frame pockets.

Get a good strong light you can hold in the other hand so you can see inside
the rails and pockets.

Make sure you take all the safety precautions the paint manuf. says and rent a
professional paint booth or have some body like some of these guys that are on
this site paint it for you.

Okay everything is super clean, wipe that air hose and make sure the painter has a
dust free suit on, wet the floor down again.

I use a binks #7 with a bigger nozzle but whatever works for you.

Spray it with epoxy non sanding primer part# dp90lf-dp402lf from ppg.

After it's dry, like weeks or months down the road if you want to clean it just wipe
it off with a california duster it will even make it shine a little

Heres the sand to blast it with.



http://www.1969supersport.com/sb04.jpg
This is the sand I use, about $8 for a hundred pounds.

that is one frame to be proud of It looks like a piece of art I hope mine comes out as nice

Thanks for the compliment. I know I put out a lot of stuff, and a lot of hobbist can't afford or won't spend the money on blasters etc.

But its easier to just put it all out at once.:D

If you sand and fill and paint it, you will spend a lot of time, but thats pretty much how you have to do it to get it right.
