I've used it for years on the interior, I clean interior pretty regularly so I don't know how well it repels dust, you definitely need to wipe down well. It leaves a nice matte finish without the oily mess you get when you use armor all which everything sticks too.

 

If I use 303 undiluted directly on my interior it will be way too glossy and uneven, and I end up spending an hour just trying to get it even. So I do a mix of like 70% water, 30% 303 and some extra towels. Thats the only way I can use it on hard surfaces inside the truck and get great results without running into problems.

 

Thanks for the tip johndog. I think I'll stick with this for the interior.

 

 

Agreed. I recently tried it for the first time and applied it, as you said, by spraying full strength onto a clean microfiber then wiping the area. Worked great.

 

Been using 303 for years on many cars. Stuff works great.

 

I'm going to have to give it a shot. Sounds promising.

 

 

Do you use it on trim or on the fiberglass as well? I have a ranger bass boat and use Phillips Pink Stuff.

 

Old thread but nobody answered apisarski lol. I've used 303 on two ski nautique 196's for the past 15 yrs. Mostly interior vinyl and rubber but I do the exterior rubber/bumper rail as well. I don't intentionally spray the fiberglass but the overspray seems to be a little messy, maybe I'm not using the correct method to rub it off. My first nautique was sold to my cottage neighbour and it is 29 yrs old and 303 has been used on the vinyl for most of it's life and the vinyl is beautiful. I love the matte look it gives on my vehicle tires and trailer tires and believe it has helped my trailer tires from sidewall cracks. It's not cheap but good and cheap rarely go hand in hand. I buy it by the gallon and put it in spray bottles.
