MAXX FILL 2K High Build Urethane Primer Surfacer with Activator - Light Grey (1 Gal.)

too thick. Directions say to not thin down. Even with a 1.7mm it struggled a bit but eventually worked once it was reduced. I'm not a pro with automotive but have used marine paints professionally in the boating and find they work better when sprayed so Its not fair of me to compare this with 2pac polyurathane. I would give this 3 stars but i'm not a professional to judge the product and it did sand down nicely and did fill stuff I wasn't sure it would fill.Update. Used a different pressure then the can recommended...lower...a lot lower. I achieved a very nice finish this time. It does shrink down a bit so keep that in mind. Seller needs to have directions other then what comes on the paint can. Also play round with your gun to find out what works best for the environment and it kicked for me really fast (about 15 minutes faster at 70 degrees then stated).After sanding my car was flawless. Again I'm not a pro in automotive and after wetsanding 600 the surface was great. Also found 75% overlap. (again not a pro so if thats not ideal for the product whatever it worked). It took out all the swirels and a few hairline cracks.

This high build is excellent for the price, Covers well, only complaint is its a little hard on the sand paper, but not to awful. It held up for a couple years now.
