The PBA should be applied by hand...if you use a PC you will use a lot of product..I tried a PC once and seemed the pad sucked up a lot of the product...some others tried also and same results...it has the consistency of hand creme
Doing by hand is fast....just apply it wait about 30 minutes and then do 105 over it and wait another 30-45 minutes ..this depends on the temps and humidity..if warm and dry 30 minutes is good...if humid wait at least 45 minutes..do a swipe test on the haze to see if dried completely...
you only need to apply PBA once to first layer of 105....no more after that..it just ensures the first layer has a clean surface to bond to and sorta hardens the first layer faster....
The PBA seems to disappear into the paint..so do not over apply thinking its not there...use a foam or Microfiber applicator to apply..you may notice the pad getting black...that's just cleaning the surface of contaminants...no worries it doing its job...it cleaning any residue on the paint.. off...
when applying the 105..just a lite spray of AW on the pad will help prime it..just a LITE spray to make sorta damp..do not soak it..only need to do once..the 105 will keep it primed there after...
Process..
PBA by hand...wait 30 minutes..
105 over the PBA by hand wait 30-45 minutes...longer if needed...buff off and enjoy..
Next layer next day if want more coats...
I am going to do a write up soon on ways to do the DG system...I have one more method I want to try and see if it works before i do the write up..the weather is getting nice now here and will try it soon..
any questions just ask...
