stripping original paint

I strip as much as I can with a razor blade scraper before starting with a DA. It helps.
I have done that many times. One trick I have learned is to hold the blade at about a 45-degree angle to the direction of your strokes. that way the blade will work a lot better, and it will not get 'stuck' as often.

i would like to completely strip the exterior of my Duster, its time to get it looking good, now i know there is more than one way to skin a cat. I dont want to use chemicals and my compressor seems to run forever when i use my D.A....that leaves my electric polisher/sander to use for the job, its variable speed and uses the sticky round 6" sand paper on a foam wheel. Has anyone used this method to strip the exterior paint or do you just use the D.A....oh and what grit should i be using...i will be following up with SPI epoxy... thanks for any advice..Rich
Nothing wrong with using chemicals. I've done it many times. Just wear gloves and be careful. Second best is a DA and 80 grit paper. I have a really good 5 HP dual stage 80 gallon compressor, and it runs when using a DA. Just be patient and stop periodically to let the compressor catchsome up. Also, change your 80 grit discs frequently. If you use them too long, the kinda turn into 220 or 320 grit discs. You may think you are saving money on 80 grit disks, but all you are doing is making the stripping last a LOT longer. When it feels like the disk is not cutting well, change it. I would not recommend the polisher sander you are talking about. It will take forever.
