I have had the TB500 for a month. I am a 1 man shop with 6C auto. It works great. The adhesive last a long, long time. Longer than my TEK BOND TBHV. Easy to apply and maintain. Very precise application. The mist does not get airborn like spray tacky and i have a fan directly on me. I only remove the big lint, strings before applying. I am 99% plastisol. I bought mine on Ebay for much less than $500.00, same company, different name. Check the ship from address, California , i think.
