Today I bought some t-Cut paint restorer, but I didn't test it on an out of sight patch and the paint seems to have bubbled out in some areas

Weird to describe, it's not bubbled from the inside, it looks like the paint already had bubbles in it and they've popped, leaving very small crater-like texture on the surface. I've noticed it's happened in about 2 places only about 1/2cm squared. It could've been there before but I just haven't noticed, has anyone else noticed this problem with T Cut before?
Anyway, I don't think I'll use T Cut again because it stinks and because it was in direct sunlight it's left a few marks on the roof where the sun's baked it. You can't really notice until you get close up though.
So what do all you lovely people recommend as a polish or wax (or both?) after you've washed the car? Should I wash & wax it (with the 2-in-1 stuff I already have), then polish it, and wax over the top to protect the paintwork? If so, what products do you recommend? Bear in mind it's a daily drive not a show car or anything but I want him to look shiny and nice
