I have a 35 foot Georgie boy that I want to use red max 3 on. I have read many posts and think this is the way to go.
Question 1 - will the TSP hurt the painted surfaces,windows or anything else it gets on. I only want to Red Max the fiberglass and use standard wax on the paint.

Question 2 - can I do the RV in sections? I want to do the nose cap and rear cap first, but will I mess up the front and rear by cleaning the sides later?

Thanks, Gary

I have a GB also with painted compartment doors, probably like yours. I had no issues with the anything on the painted areas.

I don't know why you would want to do it in portions rather than bite the bullet and do it all at once. Physical restraints may hold you back but if not I'd go for it and get it done. I did mine in about 8 hours and that included down time for drying after the wash down. If you do complete it in sections I don't really see a problem. Once the RMP/ZEP cures it is pretty much bullet proof.

One thing that sped my application time down considerably was having DW do the rag dipping. I'd hand her the old one and get the new one and we zipped right along. Two years and it looks great. I had to re-apply it to the refrigerator cover and engine cover. It was obvious that my prep work (which is everything) lacked in those two areas.

Hello Poppie, Just make sure not to leave the tsp (Trisodium phosphate) on for too long and make sure to rinse the entire unit very well to aviod any issues. The product can be some what caustic in it's strongest form. It's great for surface prep because it'll run a ph level up to 10ppm and remove any grease, mildew, and funk from your surface so as to allow your paint sealant or other coating to adhere. Good luck

Another GBM here - Red Max/Zep that whole baby!
Do the prep work and follow with multiple light coats - Long process, but results are worth it!

FWIW: I prepped mine with just Bar Keepers Friend , it removed all the old wax and oxidation. (Don't use on aluminum,- Oxalic acid). Rinse well. RM3 has been on for over 3 years, with- *no problems. Touch up 1 or 2 coats annually. Applied RM3 to fiberglass and decals, used regular wax on painted cargo doors.

*Had an area on the top of the front cap that flaked after the first year, due to poor prep...(Hard to get out there). Cleaned again with BKF and a little more effort. No problems since, and cleaner did not affect other areas of RM3.

Hey Hooligan,
What type of prep have you been doing before your touch-up coats?

I've always used Simple Green. Scrub the roof and then wash the sides , apply the RM3 to the sides after they dry. I use Nu-Finish on painted cargo doors.

I wash the whole Rv several times a year, does not seem to affect the RM3.
