How long untill paint cures?
Posted by Calmo2 on Wednesday, February 01, 2017 8:03 PM

Hello; I am just getting back into the hobby after 40 years, and now I am retired so I have some time on my hands during the winter months. I have just painted a 1965 Chevy Impala SS 396 just like the one I used to own way back, with Tamiya acrylic paint and was wondewring how long I have to wait for it to dry untill I can put on a clear coat? I am thinking about using either  "Future floor care" or "Tamiya clear" Any advice would be appreciated. Thanks.

Hey Calmo2

Some may say you should wait until you can't smell any of the solents coming from the body (the sniff test) ..... the argument would be you could be trapping the gassing of solvents which to some degree could be true, however the trapping of solvents is typically due to not waiting the required time between coats of any finish you are appyling.

The truthful answer is you can apply your clear coat at any time!

I have never used Future or Tamiya. The Tamiya would follow the rules above!

Scuff the exisiting surface with 1200-1500 grit paper wet followed by a grey scuff pad, rinse let air dry and apply your clear.

Tip: Place your sanding water In a container and add a few drops of Ivory dish soap. The soap acts as a lubricant, prevents loading of the paper and makes sanding so much eaiser.

I hope this helps!

I have never painted a car body with Tamiya acrylic so I may not be the best person to weigh in here, though coincidentally the model on my bench right now WILL be painted with this paint. I would think that at least two days should do it, but I tend to err on the side of caution and wait longer than the minimum recommended for any paint. I will probably wait a week before I attempt to polish it out.

Here is some solid advice though, Use Tamiya for clear instead of Future. Future was fairly popular a few years ago among the community, and I have seen some great finishes done with Future, but it has its issues. It requires developing a technique for applying it and is much less forgiving than proper hobby paint. I used it on one build and experimented extensively to learn its behaviour prior to applying it. It naturally flows out nicely, enough that most people apply it with a wide brush or even a cotton ball, though I used an airbrush. However it never stops flowing until it sets up, meaning most of the product you apply will run back off and need to be blotted with a paper towel etc. This makes the finish very thin, and since I intended to polish out the clear coat I tried applying multiple coats, but subsequent coats seem to reliquify some of the existing coat. The result was a mess that I did manage to polish out, but I found the result no better than normal hobby clears. The aggravation and the results did not justify the cost savings. I don't wish to deter your own desires to experiment with this stuff, but for a new or returning builder I will recommend against it.

I do keep some around the bench, though. It has many other uses. I use it as an adhesive for small items on the body such as PE scripts, and especially for small clear parts such as headlights, taillights, etc.

Thanks Guys: I will try your method Jimmy. I found some wet and dry paper all the way down to 2500 so I will try a light sanding with the 1500. I think I wiil wait at least 2 to 3 days before I apply the clear. Trevor, I already have used the Future on a model of a 1956 Ford Victoria painted the same colour as the one I used to own and it turned out pretty nice but I think I am going to try the Tamiya clear and see how that turns out! I will go to you-tube and see if I can find out if I have to thin the clear or put it on straight from the bottle. Thanks again guys, I appreciate all your help. Have a great day!
