Is there a way to remove paint from a motor besides sandblasting? It leaves a rough finish. And I don’t want to mess with doing it myself.Thanks
July 24, 2020 at 10:04 pm #209755You can soda blast or glass bead blast which doesn’t leave as rough a finish as straight sand media blasting. You can also use a chemical paint stripper but it’s a little messy. On my current Fastwin restoration, I used Citristrip stripper – it worked real good on stripping the color coat but had a tougher time removing the original zinc chromate primer. I finished up removing the primer by dosing it one more time with the stripper and rubbing with steel wool – came out nice.

July 25, 2020 at 2:23 pm #209822Thanks bob!! I knew you’d know. That looks like it works well. I’m going to do that. I tried the sand blasting but it was messy and fun kept clogging with moisture. How many gallons does it take for an entire motor? Thanks bryan.
July 25, 2020 at 3:15 pm #209823Doesn’t take much at all. A 64 ounce jug should do it. I used it on just the big pieces – cowl, lower motor pan, exhaust housing and gearcase only and had almost half a bottle left.

July 25, 2020 at 8:56 pm #209851Ah, the unsung hero — walnut shells. Instead of sand or glass.. removes paint only, not metal. not nearly as messy as chemicals, and is eco-friendly.
I bolt blocks of wood across the manifold studs.
July 25, 2020 at 9:34 pm #209862Can’t wait to try it now!!! I have my next victim picked out. A 56 7.5 Johnson.
July 25, 2020 at 10:21 pm #209865Haven’t tried walnut shells before – have to do that on the next project.

I bought some citristrip tonight. Going to give it a try soon as I clear out a few motors in the garage. Thanks!!
