Clear over plating?

[Sledsel]

Has anyone clear coated over kit plating with no yellowing? I want to clear my Texaco tanker to keep it from dulling or wearing off over time.

Any suggestions?

I've clear coated over chrome using Tamiya clear spray, and I have yet to see any yellowing. I have seen yellowing with the older Testor's and Humbrol enamel clears, but the modern lacquers and acrylic clears are much more forgiving.

Great to know. Yes, I clear coated the chrome on a '49 Mercury and it yellowed on me. Granted, this kit was done 30+ years ago.

Can the acrylic be painted over enamel? I have a kit I cannot find the orange I want in lacquer but will need cleared. The other color is white.

I have been using Future Floor Polish on grills, bumpers, and even windows for a long time with no problems. This is something I learned from another builder here on the forum a long time ago. I'll clean the part to be sure there is no lint or anything else on the part. Then dip the part in a small dish of floor polish. I use small alligator clips with a mounting rod made from cut lengths of old metal coat hangers. This provides me with a way to control the part I'm dipping and use the rods to mount the parts to a wooden board that I have drilled holes to hold the rods until the parts can dry. I suggest using a paper towel to lightly dab the edge of the part to remove the runoff from being dipped. Usually it will take at least an hour or more before they are dry enough for handling. You might try this a couple of times with a left over part to see how it works for you.

I've been using lacquer when I want to clear chrome. I think the last I used was Rustoleum rattle can which is gone now but came out fine. Also with the airbrush,, Metalizer clear which is also lacquer.

By the way, Tamiya acrylic clear is very clear clear and put down right it dries with a wet look over paint ( have not tried it on chrome). It's a bit more factory or old car/natural looking when thinned with alcohol than with lacquer thinner or X-20 thinner. Well, IMO.

In my painting experience lacquers that have a yellow tint will, over time, turn yellow. That is probably why your old clear coat yellowed. It seems today's paints are pretty much clear. I'd suggest putting some of the clear you plan to use in a glass jar to see if it looks yellow. If it's not yellowish it SHOULD not yellow over time. I can't guarantee that though.
