Post Not so much construction......
.....but a bit of a make over.

I've a CAPCO SPC 300 atu and whilst its mechanically sound, the case and dials need some TLC.
The case case is plastic and heavily marked in places. Any recommendations to prep and spray?
Also, the metal knobs/dials are dull/oxidised and I'm not sure what will bring these back to looking a little shinier. Again, any tips?

Its a cracking ATU and well worth spending some time restoring.

Thanks in advance.

Get the case powder coated, bloke in Redditch I use.
Bring the knobs here, spin them up in lathe with some polishing pad.

I have sprayed many plastic cases, including RC transmitter cases, phone cases, food processors, toys, speakers, portable radios.
The finish will depend entirely on the preparation. If there is a mark, it will show if you don't smooth it first.

Scrub it with a good detergent, when it's dry clean it with IPA (some people use petrol, but that must be very unsafe, so I would never do that :) )
During and after the cleaning, don't touch it with your fingers.

Then prime it with plastic primer, and rub it down again. Clean, prime and rub until you have a perfect primer finish. Clean and apply the top coat in thin even coats. If you want a good hard shine, finish it with clearcoat.

Bake it for a few hours at 60-70C (careful of the type of plastic)

With care, it will last as long, if not longer than the original.

Don't do it on a windy dusty day, if it is cold, warm what you are spraying (and the paint can) before spraying or between coats, all passes over what you are spraying should be at an even speed (ie don't stop or change direction while the spray is directed at what you are spraying, and don't press or release the spray button while it is pointed at what you are spraying)

I have found Halfords can paints to be of a consistent quality, expensive, but at least it is consistent. And easy to go and select a close colour.

Good advice above.

The panels are pressed steel so far as I can tell, so that makes life easier. Personally I'd chemically strip all paint from it using a decent paint stripper, flatten it with wet and dry, using gradually reduced grades down to 3200. Prime it in grey... give 2 or three coats... flatten the primer with fine grade wet and dry. Choose a matching top coat, and paint it.


Paint spraying is a skill, and no matter how well anyone writes instructions.... you'll need to practice to get a decent finish. The above advice regarding being clean, and being warm is good advice. Do not spray outside or even indoors in a garage etc if the air is damp... it will "bloom" and look terrible.


Most SPC300s I've seen have a gloss grey finish, but whether that's original or not I've no idea. If it is... you may even be able to give one final coat of grey primer, then s[ray it with a top clear coat lacquer and polish it.


As for the front panel.... There were a few versions of the SPC300... but the lettering can be restored using either the toner transfer method, or by getting water slide decals made. Both require skill and practice to apply, and the toner transfer method required specialist equipment. It can be done though, and PM me of you require help.

Both front panel methods require the text and graphics to be created on the computer, so a good, high resolution photo is the best starting point there. Get in touch if you require help with the front panel.

Knobs appear to be turned alloy... so as per post #2.... someone local with a lathe :)

A good video on the Decal Pro FX toner transfer method of creating and applying custom bespoke graphics here...

Warning: The video may make you seasick LOL

Decal Pro FX website here...

Out of the two methods, in your case, the Decal Pro FX method will be best able to restore a perfect factory finish.

Many thanks for the tips, offers and suggestions guys. I think I'm going to look for somewhere local to coat the case/covers. Not sure how much to expect it to cost though.
