How do I get it all this paint off?

I have a 1 ton crew cab that had been repainted some time before I bought it and has now started to shed it's paint.
Looking at the areas where it's peeling off, it looks like the stock brown paint wasn't even scuffed before spraying it.

I can knock some of it off very easily with the garden hose while washing it.
Any ideas what I can do to at least get this off so I can restart? I'm tempted to use a pressure washer for the bulk of it.

Thanks everyone

I hear chopped walnut shells or plastic beads work very well. They are quick, cheap, and wont damage chrome. My truck was painted with latex or something gummy like that so I had to use paint stripper, a putty knife, and a heat gun to get it stripped. I have had it for nearly two years and still haven't gotten near getting it painted because of the amount of work involved (and the fact that it has maintained daily driver status through the whole ordeal). It's going to take even longer because I decided to remove the bondo I used in the larger dents and fill them with lead.

'media blasting' is best. sand will work, but heats the metal up more and may warp it. godd old fashioned sand paper and elbow grease it tried and true method.

any large amount of blasting should be done with teh car apart - you will get blast media everywhere, and that will create problems.

chemical stripping you can try...toxic hazardous and you need to know what you are stipping to pick the right chemical. and you MUST get all the chem off or the new paint won't stick.

I have used aircraft paint remover on over 50 cars. Works great.After done I clean w/laquer thinner & prime w/epoxy primmer(PPG-DP)......Don

On cars with paint flaking off I use a single edge razor blade in a scraper. It takes about 20 minutes to do a panel this way (hood. fender, etc.) It doesn't work where bodywork was done. It takes a little practice to get the blade at the right angle and not dig in to the factory paint.

I accidently stripped a quarter panel on a 58 Impala with a pressure washer so that might work on your truck.

Both these methods will only get down to the original paint. To get stripped down to bare metal I use aircraft paint stripper. Always use rubber gloves and eye protection with this stuff and a respirator if you don't have good ventilation.

i had a 72 buick it was flaking bad so i used a single edge rezor and i took it down to the original primer and than i was good to go with the bodywork.

Thanks everyone, I think I'll try a pressure washer to take the bulk off and then a razor to strip the stuff that doesn't blow off.

That should do the bulk of it and then I sand the stubborn parts off from there.

Thanks again.........
