primer over regular paint
Hi,
I've primed my Tamiya Toyota Supra and I've sprayed it with TS-17 (gloss aluminium paint). However there were some bubbles in the paint and also the paint was too thick at some points. I've sanded the thick paint off and I sanded the "bubbled" sections, and now the paintjob is, off course, butt-ugly. I now want to repaint the car, but should I sand it entirely and then prime it and paint it, or could I just re-prime the sanded sections and then spray TS17 over it? So basically my question is; is it possible to put primer over regular paint?

Re: primer over regular paint
I would use some oven cleaner or westley's bleach white, or some castrol superclean to just strip the paint and start from scratch.

Re: primer over regular paint
As long as the primer is the same type as the paint you used, you should be alright.
As mentioned though, a safer alternative would be to strip the paint (see the Car Modeling FAQ on how to do this).

Re: primer over regular paint
How much of the model did you sand?
If its only a very small area I'd make sure it is well smoothed and try a finish coat over the whole model. If you have sanded a huge section and it will be noticeable, you really need to sand the whole model, prime and then repaint.

Re: primer over regular paint
strip it of, much safer and if you prime and paint again you will have a lot of coats on it, maybe to much.

The deciding factor should be how much paint will you have to build up to make the color uniform.
TS-17 will require a few coats to make it look uniform and may end up obscuring some details or just looking thick. If you were shooting a more opaque color I'd say just paint right over what you have done. Otherwise it would be best to strip it. Try 90+% rubbing alcohol, oven cleaner won't remove TS paint. If you still want to prime and paint, used the Tamiya Fine Primer and you can blend the Aluminum color over it.
