Need Rattle Can Troubleshooting Advice (1 Viewer)

[NMC_EXP]

Am painting the outside of 4 steel wheels. Prepped the original surface and primed with Rustoleum Painters Touch Ultra Cover flat gray primer. Prime coat was smooth.

Top coat was Eastwood Rally Wheel Argent Silver aerosol. Painted in the garage. Temp was 67 deg F. Paint cans room temp and shook them for several minutes. Eastwood says several light coats from 8-10". That's what I did.

First 3 light coats looked good. Switched to 2nd can to finish up and two more light coats left a finish as rough as 60 grit sandpaper.

This Eastwood aerosol paint has the old 1/4" valve button and is hard to push. Arthritis was bugging me so I think I was not pushing the button down all the way for the last couple of coats.

Questions:

--Can only pushing the button in part way cause "dry spray"?

--What else might cause this?

--Make sense to wet sand and start over?

Thanks

Are you sure it was dry spray and not a compatibility issue with your primer? I’ve never seen a dry spray issue that left the surface as coarse as 60 grit paper. I have seen compatibility issues that didn’t appear until a few coats were applied, however.

I just researched those two products and it appears you sprayed a laquer over an alkyd. You can expect compatibility issues with that combo. You’re going to have some work ahead of you to get that stuff off and then respray with a compatible primer/paint system.

If you have issues with holding the nozzle down, the handle's that slide around the top of the can, and over the nozzle, with a full grip to squeeze allow you to use a better sweeping motion and move more naturally. It also allows for sharper starting and stopping of the spray.

I was indoors with no air moving when I sprayed the topcoat. When I cleaned the area I was surprised at the amount of paint dust on everything in the area from less than one can of paint. This Argent wheel paint contains powdered aluminum, may have something to do with it. Starting to suspect the rough surface I got was contamination by dry paint dust. The first one painted was OK but the other three were rough.

I understand the potential problem with primer and top coat compatability. I wet sanded the rough top coat down smooth. Now after two weeks the remaining topcoat is tight and no signs of delamination, peeling, bubbling...etc.

Also bought one of those rattle can trigger gadgets. Tried it out and decided it's a good thing.

Thanks for the help.
