[quote]I also picked up some sprayway glass cleaner, we will see how that works out![/quote]
Some glass cleaners are very similar to some water based cleaners anyway – at heart a water/alcohol mixture.We work in a similar way to that mentioned by Jimmo – a clean with a solvent based wax/silicone remover before we even start the job (DeBeer 1-951), another once the prep is finished, but before masking, then a final wipe down with a water based cleaner (1-851) before paint.
As said by Jim C, they each remove a different set of contaminants, so using both is a good idea, and I leave the WB one until last as it gets rid of finger prints etc from taping up, and it’s also anti-static.
I was also recommended to use a Sealer, i am sure that this will help seal off contaminants out as well
a sealer CAN hide some problems BUT #1 you should try and get rid of the problem and not attept to hide it because it can come back and bite you later and #2 you need the right kind of sealer. there are 2 kinds of sealers, primer sealers and the ones that spray more like a clearcoat like rm’s dp31. the primer type are much more forgiving and will hide some problems of a poor prep or area to spray. the glossy resin type should be in a clean booth only as they cant really be denibbed. spi’s for instance is a primer type and would better suit your needs as you can denib and dry sand it in 10 minutes. hok’s is also this way. there are many others as well just be aware of which one you are buying. i always spray a sealer down. helps with adhesion and its a must for what i do because i am always spraying candies and they bleed. spi’s or hok’s might be a good option for you as you can kill 2 birds with one stone and use it for your primer as well as your sealer. its all in the reduction
good tip, still waiting on the waterbased cleaner (wasn’t in stock at jobber). Still have to give that a try as well. I agree with you that the problem can still exist Jim. Thanks for the tip on the two kinds of sealers. That is something i am going to look into.
