DIY Tinting - post fit, thoughts?

[dieselj]

I did mine, sides were fairly straightforward, 2 goes at back window using heatgun method. Turned out fine

How did you do it though....??

Vertical, horizontal, from the inside, outside?

i did mine. its best done inside a garage. i bought the pre cuts in limo black and a roll of limo black for a tenner just in case i needed it. side windows i took out. dead easy and did them on a table. back window is tricky. had to do that twice. but it turned out perfect. I have now done 3 cars after people said how well i did. and i even had a visit from a pro tinter whilst doing my lads car in the garage who was very impressed with the materials and my work. 
watch the you tube vids. dont be afraid to use lots of soapy water. it looks a mess at first but when it dries its superb. get a decent squeezy to apply the film. and also a decent craft knife. i didnt need to use heat either on the side windows. i just applied straight on to the inside. the rear i used a paint stripper air dryer thingy. if you aint got one, cheap as chips from screw fix. when you watch the youtube vids it shows how and why you apply on the outside first before putting on the inside.
ive done 3 cars and i am wanted to do more. its getting space in my mates unit thats the problem. ive spent £100 on tools and materials but ive done 3 cars with that.  
its not easy. every back window ive ended up doing twice. 
give it a go. 
top tip. if you are not happy when you apply the tint, don't let it dry. its a bugger to get off.
