Can I Use Future Over Lacquer Primer?

[Len Woodruff]

I am cleaning up the ejector pin marks & the copyright from a Revell 32 Highboy chassis & would like to spray Future over the primer to "seal" those marks from ghosting.

Len, the lacquer primer may cause it to ghost even before you put on the Future because of the hot solvents.

Here's a sure fire way to prevent ghosting I learned from Ted "Chopper" Lear...........

First sound down the markings and ejector pin marks per usual.

Next you want to take some liquid cement (Ambroid or Tenax is best) and brush over where you did your work. You'll notice that where you sanded, the markings come right back again (ghosting).

Once where you've brushed on the liquid cement is dry, sand that area again, What you're doing is getting rid of the "memory" of the molded in areas. Since the liquid cement is a hotter solvent (naturally!) than the lacquer primer------once you paint that area, it should not ghost again.

I've used Future BTW directly on the bare plastic with no ill effects...........you've seen the Magnum I'm working on (and a few others) and they were all done this way. You could probably spray the Future on the primer with no problem, but I like that extra protection in the beginning to save any hassle down the road.

HTH!

So that is a yes I can use it on top of primer?

Len, as I mentioned before, it'll probably be okay to spray it over the primer with no ill effects. I've not done it that way as I've described.............to be on the safe side, take a scrap body and test it out.

I wouldn't count on Future to seal anything. Future is very, very mild and really should only be used as a top coat. I think just about any paint you would use on a plastic model is hotter than Future and it might dissolve it and cause worse problems than ghosting.

David, I'm not meaning to sound contentious, but I've done the following 4 models shown with hot automotive paint by spraying Future Floor Wax directly on the plastic with no crazing whatsoever. The paints came from a local automotive paint jobber who had warned me how hot the paint would be on model plastic.

I told him I had a cure for that ............and I'm sure it would work out as it did. I had tested it out beforehand, so I knew there would be no surprises.

Those that know me and have seen my models in person can vouch for this. If you check out my Fotki album (2005 Mustang Buildup) I even demonstrate how this was done.

You can see for yourself.................

The Revell models in particular are acute with problems because the newer plastic is soft, but I'd recommend it even for older plastic such as my Turbine Car, because there was some bodywork done on that one likewise.

I learned this trick from the military guys who've been using Future to seal their plastic for many years now, so they especially would know.

Here's a very interesting website that shows all the nice things that can be done with Future.

Bill, I'm not surprised that Future seals plastic against hot automotive paints; Zinsser BIN seals it too, it's a shellac-base primer/sealer and I would imagine that regular old shellac might work all by itself. It's probably because Future is a dissimilar chemical makeup is why it's not affected by lacquers. The same goes for paint washes; use an oil-based wash over acrylic, or an acrylic-based wash over lacquers/enamels to avoid affecting the underlying paint.
