I have been told that the best way to apply the paint stripper to get the most effect out of it is to spray it on and apply heat, then use a high pressure washer to remove it.

The type of paint being stripped is automotive Imron - its tough stuff.

need some input - thanks
 

The two part stripper: You mix the two parts together and apply. Spraying is a great way to get a heavy and even coat, however you have to be very careful about where the aerosolized fumes are going and with NOT breathing them. Got to use an airless and the equipment has to be rigorously cleaned afterwards, unless you can use that spray bottle method sold with some strippers. The spray plastic bottles clog up pretty fast and the plumbing in the head goes south real fast around that chemical bath. You might also try rolling it on, using a heavy nap, varnish roller. I did a major strip of a '49 Jag XK120 which had been painted seven times. We used plastic sheets to cover a heavily coated area and inhibit the drying out of the stripper. Careful 'chiselling' off of the paint is also a must on aluminum. You got to be careful to not scratch up the aluminum beneath and we found a 1" metal scraper, sharpened frequently worked the best by gently pushing it thru the softened paint.

George is right about thorough wash down afterwards. You have to use the right alumi-prep solution and numerous times to really get results. Zinc chromate primer and even epoxy primer over it does help the final paint adhere.

The idea that you paint this stripper on and it all just comes off with pressurized water spray is not exactly how it works. You have to coat and recoat many times over Imron. You only pressure wash after you get most of it removed. Use cheap stripper and you expose yourself to Methyl Cloride (bad stuff to breath if you are trying to avoid cancer). Plenty of ventilation is in order, no matter which type you use. Good luck. Be patient and wash thoroughly everything after being exposed to this stuff. Bad pizza.
