I recently just did this to a work truck. I used a heat gun and a plastic razor blade then used 3M adhesive remover and wax and tar remover to loosen the left over glure then buffer with Megs D151.
I was thinking of buying that exact one. to replace my old noisy Husky. The Husky has a larger tanks and is 150 lbs but It so noisy. How is the noise level with these Harbor Freight ones?
