over spray on jambs on repaint

How do you guys do a same color repaint on a car and not get over spray on the jambs?
Do you tape it close to the edge and paper off everything and shut the door, trunk, hood?
How is this done with out leaving a tape line?
Need help on this please.
Thanks.
There are several ways of doing it, and each will have his own preferred method.
As you say, firstly I’d paper and tape up the insides. With most jambs you can get away with 6″ paper easily, but you could completely cover everything if you wished. Keep the masking around 1/2″ from the jamb edge, as you’ll sort this with the next stage.
This is where things vary a bit. The easiest option is to use to use a foam edge tape like the one from 3M. This looks basically like a piece of foam rope, with adhesive on one edge. This stuff blocks up the jamb gap to prevent overspray going inside, but one major downfall it has is that paint can stray onto the glue section and leave a hard edge against it.
To cure the above problem 3M have brought out a new advanced verson, which is more like a flat tube, and the glue edge is always kept well away from the jamb edge so there’s no chance of a hard edge. I use this stuff every day as it’s quick and effective.
Another more old school way is what we in the UKcall French Masking, but I think you guys have another name for it. I’ll take a length of 1″ tape, and fold about a quarter inch of it back on itself. This then leaves you with around a half inch of tape that you can stick down, but around a quarter inch ‘flap’ that doesn’t stick (jees this is hard to describe!!) Stick this tape so the your folded edge is right up to the edge of the jamb, and a small amount of paint will feather under it leaving you with no hard edge. If that lot doesn’t make sense, have a search for a new 3M product called transition tape. Basically it does exactly the same job, but they can charge a hell of a lot more for it! :lol1
If I’m doing a high quality job (rather than just my normal high speed production stuff), then I’ll use both of the above methods. Some french tape to stop the hard edge, and some of the foam to bridge the gap and prevent overspray going into the jambs (and just as importantly, stop dust and dirt blowing out!)
Hope that makes sense fella :huh:
I hope he doesn’t mind me using this video as an example, but jimmo is using what I call french masking on this repair, to prevent a hard edge on the body lines he’s painting up to. Should make a lot more sense than my description!

Thanks you Andy. I watched the video. I tried using that stuff to blend the clear but it ran really easy. I was told to use it very lightly and it looked to me that he really sprayed it on heavy. I was holding the can back pretty far too. Now I don’t like it. lol
Anyways, I understand what you mean by folding the tape over. If you spray from the back side of the tape fold the spray pattern isn’t as heavy and doesn’t cause a (hard) line. If that makes any since??? :wak
except if your french masking … you use the french side of the dog food bag :lol1

Ryan did a Video on “Back masking” awhile back… I can’t find the topic for the life of me…
I gave up on the Sites Search engine. :lol1
And just resorted to finding is Youtube page…Here’s a video of him Folding his tape for back masking.
http://www.youtube.com/watch?v=Qdz0xuGN2LEwow, this site is truly amazing. I ask a few question on here and people really put effort into helping out.
Thanks guys.
That foam tape looks like something you would use for weather striping. how much does it cost?
As with everything in this industry. (Especially when it has 3M’s name on it) It’s pretty pricey stuff.
For the 3M soft edge You’re looking at about 50-60 bucks for 27 yards.
Some of my local jobbers it’s as high as 75.That is exactly why a lot of guys chose to use the more time consuming Back masking technique…
Those are really good answers guys,I have tried every method and the best one I have found is called the ezedger(www.ezedger.com).This contraption will take a roll of 3/4 inch tape and hold it like a masking machine,when you pull off a length of tape it will automatically fold over the edge to whatever size flap you want.It only cost me about $60 and it works better than anything I have ever tried.I only use it on newer cars or a high dollar resto,not the regular production crap.
that ezedger is a pretty darn nice idea. very well thought out.kind of pricey.
thanks jayon
Here is a link to the way I mask. Rat already put up the video. This does the same thing the ezedger does. I have the ezedger and just do it by hand because it’s faster for me. I think it is the same thing Andy is talking about also.
