Painting numberplates

[ronhatch]

Hi all, I am currently engaged in bodywork but every so often I like to take a break and do something different from welding filling sanding etc. and this time I decided to renovate the number plates. I have the plates with the raised ally numbers so I drilled off the numbers and cleaned them and silver painted them, they look great. I stripped the ally plates and under coated them but got a reaction (bubbles in the finish) so I stripped them and this time used an etch primer, same problem. I am using black celly and I assume this is reacting with the ally but I thought the etch primer would seal it. Any help would be appreciated as a mental diversion is driving me nuts !

Modern primer in tins does not dry properly unless you keep the plates near a source of heat for a couple of hours. Bubbles are likely to be condensation. For the ally numbers: polish then clear gloss retains the original look and is likely to save you some speeding tickets.

Thanks for the reply.Unfortunately there was not much paint left on the plates hence the repaint, conditions were dry and warm.

I have just painted a pressed aluminium and an original Ace plate with raised letters following Forum advice (http://www.tr-register.co.uk/forums/index.php?/topic/48185-repainting-pressed-aluminium-number-plates/?hl=paint). I used Halfords satin black spray followed by some old clearcote left over from my MG Metro on both and had no reaction.

For pressed aluminium plates I'd coat the raised digits with liquid Latex and when that's cured I'd spray

the plates with Halfords gloss black paint. Remove the latex coating and polish the digits.

It worked fine for me.
