I’m getting a really ugly reaction when spraying Tamiya TS red over Mr Hobby aqueous white primer, anyone else run into this? Also, what’s the best way to strip the TS paint so I can start over?
I think you’re trying to spray lacquer over acrylic. The can says ‘TS SPS’.

I have good luck stripping paint with Super Clean. Its available at Walmart in the automotive dept. Comes in a one gallon container for not much money. Just submerge the parts you want to strip in a bath of the Super Clean. It should come off in a day or so, with light brushing occasionally. Doesn’t hurt plastic and should work on the water based primer too. You can re-use the cleaner repeatedly.
Some people use oven cleaner instead. Just put the parts to be stripped in a sealable baggie and spray the oven cleaner in there with the parts and seal it up.
Hope this helps. Good luck!

Agree with Peter - Super Clean is great for stripping paint and chrome off plastic!

You have sprayed a lacquer paint over a water based acrylic that’s what’s causing the problem. Tamiya paints are sometimes reactive to other paints , even if they are base paint. For instance you cannot use a Tamiya acrylic thinner with a AK acrylic paint because it will curdle or go lumpy you need to use distilled water or a AK acrylic thinner, because Tamiya acrylic is a alcohol based paint. Sometimes a quick google search will give you an answer if you want to combine different brands of paints.

Oh this is perfect, thanks 
I’ll take another crack at my kit but I’ll try with an acrylic red instead.
I always use a lacquer or enamel base primer,gives a much better bite and adhesion for future coats and masking.Tamiya and Mr Surfacer work great.

I use SuperClean, too, and if you don’t want to immerse your model, you can apply it with a brush or with a paper towel. It just might take longer, with multiple applications, to remove the paint. I have used a small brush to apply SC on a figure and remove paint from a small area without having to strip the whole piece.
A big advantage of SuperClean over oven cleaner is that oven cleaner is once-and-done. You can’t really use a batch more that once. You can use a batch of SC multiple times. I use glass jars of various sizes, or old glass baking dishes, to make “baths” of SC to work on various pieces.
And it has household uses as a grease cleaner, so for the money, it has a lot of value.
Best regards,
Brad
