I decided to give the 105 a try today. It was my first time really getting to work with the product. I used a light cut foam pad and the 105 on a rotary for the correction work i had to do. I was impressed with how good the paint looked after using the 105. The only issues i had with the product were the dust and the product gummed up pretty fast which left it unworkable at times. What is the trick to keep it from gumming up? I tried some paint spray but wasn't to satisfied. Are there any other tricks or things i might be doing wrong?
