Dash Cluster Restoration
If you wet sand the lenses first then buff them you will get better results.Not familiar with your dash setup,can the lenses be removed from the panel itself?The ones i have done usualy are melted in by "spotwelds".If you can take them apart thats your best bet.Dremel.Cut the welds.
Start out with some 1200 grit and work your way up.If you finish with 3000
grit its alot easier to polish.I use my regular buffer in the vise and run the lenses across it.Do this and they will look like new again.Dont be intimidated
by removing those lenses,its easier than you think and can be stuck back in with an epoxy.As far as the painting,mine is rattle canned,i dont think you need a clear coat,use the duplicolor line and you will be fine.they dont see weather,so just take care when cleaning,wax treated clothes work great and wont scrape your lenses up after they have been polished.Takes some time but worth it in the end.
