i've been using the twins for a few years now with a 7424 and have attained some pretty darn good results. i've had a roatary sittin in my tool box beggin me to just get rid of the fear and go for it!. well, i did a complete repaint on an 86 blazer about 6 weeks ago. well, i sprayed it about 6 weeks ago. spent many hours over the 4 weeks before stripping to bare metal, rust repair, inner and outer fender replacement, lots of time getting the door skins smooth and all the good body work to make it look good with new paint. the truck went to original dark metallic brown and 1st paint job with my new devilbiss tekna gun. i had OP in spots so wet sanded through the grits to 2500.
now the sad part: i didnt have enough m105/ 205 to complete the truck! bummer. didnt think about it til it was time and the owner was picking it up in 2 days. not enough time to get the product delivered( no shops around that caryy em). so i tried another brand that was carried at the shop i get my supplies from. looked good for a few weeks. owner called and said he wanted to stop by and have me take a look at the truck. dulled out terribly. i could see that the product i used wasnt worhtwhile.
so i ordered up the m105/205 and decided it was time to try out the rotary ( using a wool pad for 105 and blue foam for 205). i started with slow speed and worked up. found a decent spped and worked up to where i was comfortable and getting the results i wanted ( removal of sanding marks that were there after the "other product" washed off). WOW!!! the time involved to do the whole truck was cut down tremendously!!! and the results were awesome( well, awesome was achieved with the da, but just took a lot more time). i had just finished with the 105 and the owner stopped by and he about fainted! i said, " please, wait til i get done with the 205 and put a glaze on it before fainting!"
i'm pretty geeked with the results and the amount of time cut off using the rotary. and at this point in time, still not interested in trying any other products!
