To sandblast or not to sandblast.....
Hi everyone,
Lucky enough to buy a spare set of calipers for my '88 944. At a great price also. And they appear to be in good shape inside. So, rebuilding is possible.
(Other shoe drop here) Trouble is they are painted and the paint is peeling and not in good shape. The calipers do not look good.
I need to strip this paint off and re-paint or leave natural. My question is: should I sandblast them clean or use chemicals? I have a sandblaster available and that will limit cost but I do not want to introduce 'particles' into the calipers. Chemicals are messy but rinse away.
What is your experience?
Thanks in advance.

Hey Pops 83...when you had them powder coated, did you take the entire caliper assembly apart first? I did just that, and now I have to put them back together with the help of a Dremel to clean off the unwanter powder coat...used a new vendor for this operation ..not sure if I like the work or not..time will tell...Thanks, Tiger

I'd recommend putting small cardboard coffee cups in the piston bores to keep the powder out and then remove them before they go in the oven. It'll keep you from having to possibly damage the piston bores when you're cleaning them up. A loop of masking tape on the bottom of the cup wil keep them in place while they're being dusted.
