Hey all,
Working on an in service T29e3 project, considering doing a whitewash over Tamiya khaki drab in acrylic (xf-51)
What should I use to seal the acrylic before hairspraying
Which white would be best and how should it be thinned if airbrushed or hand painted. And should I use acrylic or enamel ( issues with going above acrylic??)

You donít need anything to cover the base coat.

A lot depends on when you want your white wash to be, fresh/early winter, middle or late winter/early spring with only trace amount remaining. You can use Tamiya as a white coat, I would thin it more then usual and use light coats as Tamiya can be tough to take off and/or I need more water and patience. Never had much luck using Vallejo as a top coat as it doesnít flake off in fine amounts and more like giant potholes. It could also be just user error with Vallejo.

WOW! How relevant for my next project. I was just planning out my M48A5 in a winter whitewash - and your choice of subject (T29) was one I was thinking to do as well in a whitewash before I settled on the Patton. The info posted is a big help. I did a few German & Russian vehicles in whitewash but never really liked the outcome - looked chalky and too precise. I love the videos posted - very helpful

Good luck with the project

I would definitely seal the acrylic base with varnish or Future floor polish (I use Future). I also find that multiple coats of hairspray give much better control when weathering the whitewash. After weathering the whitewash coat I also like to use ivory white oil paint to create streaks that look like the whitewash washing off.

You don't need to seal the basecoat with anything. Just let it dry 24 hours and the water won't effect it. DO NOT use Vallejo for your white wash. Vallejo is a latex acrylic and will come off in big rolls, not fine flakes. For the white, use Lifecolor white, Tamiya white, or Ammo white. My personal favorite for hairspray is Aqua Net pink can. Also, you can get a cheap set of stencil brushes at Michaels or Walmart that are perfect (stiff) for scrubbing the whitewash off. Other than that, have at it and it should come out great! Oh, and a few rust streaks to finish it with burnt umber oils. If you get stuck, just ask. If you do decide to seal the basecoat with Future (not a bad idea to be safe) you're going to have to give the whole thing a coat of Dullcote when it's done, because the Future will show the basecoat portions glossy.

I'll beg to differ with Matt at least where Acrylics are used for the base coat. It is true that it may very well work without a clear topcoat before the hairspray, but the risk of inadvertently removing your basecoat is much higher, particularly if you didn't do a perfect job of cleaning and priming first. Overall, I find it much easier and less stressful to get the results I want with the basecoat well sealed. Of course, if the basecoat is enamel, then Matt is 100% correct.

Also, I've never had an issue with using Vallejo for a white wash. Just don't apply it in too heavy a coat.
