I have a foam block I bought @ NAPA. The paper side of the block has holes and the block is kind of arched to contour to the sanding surface.
Is that what your looking for??

My local hardware store had them. There were probably around 600 grit, but i just wrapped them in higher grit paper.

DuraBlock makes nice flexable blocks in various sizes and hardnesses. I got all mine at the local paint store they arent cheap but they do a great job.

I find those foam block leave to many "waves" in the clear/topcoat leaving you with the "water ripple" effect in your final finish, esp, dark colors, rather than a "flat mirror" reflection,........heres's a car that I wet sanded out using a hard rubber 3"X5"X1/2" pad/block,(avaiable at most automotive paint suppliers) and the true and tried paint stick( local hardware store, mixing/stiring sticks).....started with 1000, then 1500, then 2000, finihed with 3000 grit.....minimal amount of machine polishing needed afterwards

Sorry I misread your post wrong blocks at Harbor Freight.
Try Eastwood though.

I agree with DAYCLONA, use the best,most effective and the cheapest, paint mixing stick, it doesn't fail, foam blocks will only smooth out the orangepeel and you still end up with waves, I wrap mixing stick a few times with 2" masking tape than wrap the paper around it and go at it

That is what I use too, a 3 x 5 hard rubber sanding block, starting with 1200 grit, 1500 and 2000....mirror like results!
For Big, flat surfaces, I use the bigger 4x8 block with hard orange plastic top with 1/4 inch rubber pad underneath

Thanks, good info.
I have to redo my Coronet because of over spray and was wondering what block/pad was best for color sanding. I assume you use the paint stick in the close quarter areas and the hard rubber pad on everything else?

Correct,.....never let your "fingers do the walking", or a soft surface behind paper, or those "sanding blocks" for delicate finial surface work,.....I know there's times of nooks and crannys that you have no choice, but for the open expanses of sheetmetal, you want a resilant surface under your paper, to produce a "flat finish".....good luck on your project!

A length of rubber hose works well for contoured areas. I prefer the softer 3M pads over the hard arched blocks. Your local auto paint store should have a good selection.
I can't imagine being able to sand waves into a car with 1500 or 2000, or for that matter even 600, unless the person is either using their fingers, or the bodywork wasn't right and is revealed by blocking. Wetsanding should not be aggressive.

I have sanded many many vehicles with a foam block and never had ripples or waves....Believe me if I did our uber picky customers would be throwing a fit.
