3M claims to be durable, reliable and built with quality, I agree. However, not all disc sandpapers are the alike.
I used both the adhesive and Hookit type sanding discs and I can tell you that Hookit is the best.
Here are the pro's and cons of both:
Hookit Sanding Discs
Pros:
1. Hookit allows you to reuse the disc sandpaper more often than its counterpart
2. Works while wet and will not fall off when wet
3. 3M Hookit interface pad (part Number 05777) works great and only available for hookit type sanding discs
4. Just feels right.
Cons:
1. Only available in large quantities
2. Not readily available in autoshops
3. Can't use on Durablocks unless you have 3M's Hookit Blocks (part No. 05687, Large block)
Adhesive Sanding Discs
Pros:
1. Can be used on Durablocks
2. Available in almost all Automotive parts stores
3. Cheaper especially since you don't have to buy in large quantities
4. Can be reused*
5. You can stick to the back of your buddy
Cons:
1. Limited on times you can reuse
2. Don't drop the disc unless you want dirt and whatever else gets lifted from the ground
3. No interface pad
4. Adhesive not waterproof
5. Not as durable as Hookit counterpart
So, there you have it. If your going to invest in Sanding Discs, spend the extra cash and buy the Hookit options, it will save you time and money in the short term.
Till next time.
