Filler Prep Adhesion Promoter

Works great on plastics

Prior to I did not use a promoter as a result my dash cracked at the repair. Let's see if it stays together now :-)

Very good

Change to work as advertised

Excellent Product! Will definitely get it again!

The package came wrapped in multiple layers of plastic bags. I regret opening it indoors because the smell was horrendous. Everything had spilled out and I didn't get to use any of it. Very disappointing

Product does some heavy duty cleaning but it is harmful so factor in the extra cost of proper health gear needed $$$.

This is supposed to make a good bonding surface, but it requires you to sand the project first anyways so this is useless. Just sand your surface before putting the dash filler on.

I’m giving this product 3 stars because while it does the job, it comes with a few drawbacks. The filler hardens very quickly, leaving little working time. Once dried, it’s extremely tough to sand down and creates a lot of dust, which makes it impractical to use inside a vehicle unless you’re prepared for a major cleanup. It may work better on older cars or dashboards with fewer contours, but for detailed or interior work it’s not ideal.
